I hope I addressed all of your specific questions...In-addition, I'm actually concerned about what you described regarding her feather-health, the "constant" molting, and her lack of overall-energy that was remedied by the simple addition of Supergreens...And then the whole "Harrisons pellets and Chia seeds" as her regular, daily diet (and I got the feeling that she's not actually eating much of the Harrison's, which leaves Chia seeds and that's it, which is not at all good nor adequate)...
***As far as her feathers as they relate to her overall-health, along with the "Supergreens" issue...First of all, I have a BS in Health Science and a Masters in Animal Health Science, so I'm coming from an educated place when it comes to Physiology, Pharmacology, Nutrition, etc...I'm familiar with Supergreens, and as long as they were nothing but the actual Greens and didn't have any other supplements added to them, then what you are describing to me as far as her visibly/noticeably having "More Energy" when simply eating a daily portion of SuperGreens and then visibly/noticeably having much less energy when she stops eating the SuperGreens, is a definite issue in-regards to her regular, daily-diet and her overall Nutritional-health. Bottom-line is that giving your Green Cheek a daily portion of SuperGreens SHOULD NOT at all result in a noticeable change in her energy-levels, Period. And when you also combine this with what you are describing with regard to her feathers, this ABSOLUTELY indicates some type of Nutritional-Deficiency or state of "general" Malnutrition. She should not be "constantly molting", nor having to constantly over-preen herself due to her feathers being constantly in a state of molt....A bird's feather-condition, as well as their beak-condition, are directly-related to their overall-health, as are their "energy-levels", and the one aspect of a bird's overall-health that links their feather-health to their overall energy-levels is their Nutritional-Health. If you think about this in-terms of human-beings it will help you to understand, as a parrot's Physiology as far as their daily-Nutrition and how it influences different parts of their body does not work any differently than that of people...If a person is lacking a nutrient or multiple nutrients in their regular, daily diet, it will effect their skin, hair, nails, etc. It will effect their Metabolism and their energy levels, etc. More importantly, if a bird has some type of Disease-Process going on, or an Organ-Function issue of some kind, or there is something that is effecting a certain Gland or hormone-producing Organ in a bird's body, such as their Thyroid Gland (the first thing that I immediately thought of after reading your last paragraph regarding your bird's energy-levels and feather-health), and this is either directly causing a Nutritional-Deficiency (because it is preventing the digestion, absorption, or processing/use of a particular nutrient(s), OR is being caused by a Nutritional-Deficiency (because either the bird isn't eating an appropriate diet, or because the bird isn't able to absorb a certain nutrient(s)), then it will eventually become visible and obvious outwardly, no matter how hard the bird tries to hide that something is wrong.
***I don't know if you have an actual Certified Avian Vet or Avian Specialist Vet up there in AK, but either way, whatever Vet you do have access to, if I were you I would be making an appointment for her and requesting that she have full, baseline Blood-Work done, if she hasn't had it done in at least the last 6-months...All birds should have regular, baseline Blood-Work done at least once a year, along with a full Fecal-Smear/Culture as well...But something isn't right here with Orin with regard to her constant-molting and overall feather-health, along with her low energy-levels...Again, Supergreens should not effect a bird in that way at all, and when you combine the two issues it sounds like a Thyroid issue to me immediately...There is a list of Differential-Diagnoses in my head for these two issues, but the Thyroid being involved is at the top of the list, along with the Ovaries as well...Depending on what tests your Vet includes in a bird's regular, baseline Blood-Work, they may not need to add it, but you need to request that they test both of the main Thyroid levels along with a Liver and Kidney panels. The major Nutritional levels that could be involved in this should automatically be run in the basic Blood-Work run on a bird...As long as she is eating an adequate amount of Harrison's pellets every day, then she should not be suffering from any low nutritional levels, as Harrison's provides all the daily nutrition a Green Cheek needs for a day (as long as she is actually eating an adequate amount of pellets each day, and she is maintaining an appropriate weight for a female Green Cheek Conure, which should be somewhere between 65g and 80g)...However, if you don't think that she is eating the recommended amount of Harrison's pellets every day but rather just picking at the pellets and then actually eating only the Chia Seeds, then that could very well be her major issue, as Chia Seeds alone WILL NOT provide a bird with even close to the amount of daily vitamins, minerals, amino acids, protein, fat, carbs, etc. that they need every day to support their body's basic daily physiological processes. In reality, if you are thinking that she is only "picking at" the Harrison's pellets and then filling herself up on only the Chia Seeds, then you've got a serious issue, and she would be much better off being fed a healthy and varied Seed-Mix for parrots that is high in protein, low in fat, and that contains NO Sunflower Seeds, NO Peanuts, and NO Dried Corn kernels or pieces...There are a few commercially-sold Seed-Mixes that are very good and that provide a variety of lower-fat, heathier Seeds, Grains, Legumes, Veggies, Herbs, a small amount of Fruit, and a small amount of healthier Nuts, namely Almonds. These Seed-Mixes include Higgins Vita-Seed "California Blend", Tropimix (which also contains Tropican pellets), Higgins Safflower-Gold, and a few others...The main thing you have to look for is NO Sunflower Seeds of any type AT ALL (these are never anything but an occasional treat and that's it), NO Peanuts (the fattiest Nut of all that provide little nutritional-value and that also commonly carry a type of Mold that is Toxic to birds), and then NO Dried Corn of any kind (nothing but tons of fat and that's it, no nutritional-value, and is only used as a "filler" in the cheaper Seed-Mixes)...While it is ideal for our pet birds, who do not fly for 8-10 miles every single day like wild birds do, to eat a "Natural"-flavored pellet as their daily "staple" diet (as opposed to a "Fruit"-flavored pellet that is full of nothing but sugar and fat) or a Seed-Mix which are usually full of fat, if we are feeding our pet-birds a high-quality, Natural-pellet like Harrison's, TOPS, etc. but they aren't really consuming the amount of these Natural-pellets that they should be, then we can actually end-up making our birds Malnourished and/or Deficient in different nutrients, which can gradually cause multiple health-issues over-time, and in the end really cause our birds to become seriously ill...And the problem with only giving your bird "Chia" Seeds is that while they are low in fat, they are also los in the overall-nutrition that a Green Cheek Conure or any other bird needs on a daily-basis...That's like allowing a child to fill themselves up every day by eating nothing but Broccoli. Yes, Broccoli is very healthy and provides a day's worth of certain vitamins and minerals, but it lacks many other required vitamins and minerals, and contains absolutely no protein, no healthy fat or carbs that they need every day, etc. That's why Seed-Mixes are used as daily "staple-diets" just like pellets are, because each different seed, grain, legume, etc. that is included in a seed-mix is TOGETHER providing the overall daily nutrition that all birds need...
And I didn't see anything about her eating ANY fresh Veggies, or ANY fresh dark, leafy Greens, or any grains, legumes, etc...I don't like to give my guys fresh Fruit every day due to the enormous sugar-content that all Fruit contains naturally (it's just turned into fat and stored in their bodies/livers just like the fat in Sunflower Seeds, Dried Corn, and Peanuts)...Unfortunately a lot of people think that fresh Fruit is interchangeable with fresh Vegetables and fresh dark, leafy Greens, and it's just not...Fresh Fruit should only be given 2-3 days a week and in small-portions that are IN-ADDITION TO a large portion of fresh Veggies and fresh dark, leafy Greens...But you didn't mention anything at all except Harrison's pellets and then Chia seeds...And I'm not sure whether she's actually eating ALL of the recommended amount of Harrison's pellets every day or not, which only leaves a bunch of Chia sees, which is not good...But even if she was eating all of the Harrison's pellets that she needs to be eating every day, she should also still be getting a nice, large portion of fresh Veggies and fresh dark, leafy Greens every day as well...Judging from the "Supergreens" and the Chia Seeds I'm assuming you're into natural eating, or "Raw" eating, etc., which is great for people, but it's not for pet parrots...And I guarantee that even if you drink Supergreens and eat Chia seeds every day, that's not your complete, daily diet, because if it is then you've got no muscle-mass at all, and you're severely malnourished...So you see where I'm coming from in-regards to your bird...
