i freeze alot! i make the chop and portion it in sandwitch baggies, then put those baggies in a 1 gallon ziploc freezer bag. it takes my eclectus about 3 days to eat whats in each baggie and i just thaw it in the fridge over night. i serve him this chop cold, and i try to avoid microwaving anything if at all possible because im worried that mircowaving may destroy some of the goodness in his chop i try to prepare so perfectly. i do however microwave his sweet potato servings because i will bake them and remove the skins, then mash and i put that mash into ice cube trays. each night i put a cube in the microwave for 25 seconds to thaw/warm it before i mix in his cold chop and refigerated fresh sprouts. i make the sprouts in mason jars and each jar lasts about 4 or 5 days, i just have to time it right so when one jar only has about a third left in it ill start another one and he never runs out. theyre pretty easy to keep on hand fresh this way so i havent bothered trying anything else with them.
i do not mix fruits in his chop but i did buy 4 or 5 really good looking pomegranates one day which i cut open and scooped out all the seeds. i bagged them up seperatley and froze them and they seem to have frozen perfectly! no solid cube of juice at the bottom of the bag, no freezer burn crystals, theyre apparently really good for freezing! ill put a tablespoon of these seeds into his dish in the morning, still frozen, and as they thaw he will gobble them right up! i bought a bag of already frozen organic blueberries but they were all crystally when i opened the bag and he doesnt seem to like them much.
i do find that his chop baggies need to be squeezed out after theyre thawed..ill let them sit in the fridge over night then ill give it a good squeeze to get the liquid out and transfer the chop into a small tupperware. ive tried different combinations of veggies and ive also tried adding in some uncooked 'quick oats' to the chop prior to freezing, nothing seems to prevent the juice from forming after its thawed. but squeezing out each bag doesnt bother me much. my chop usually has about 10 ingredients, and while im preparing it ive noticed that things like bell peppers and celery make ALOT of juice, but he loves those things so i choose not to exclude them just because theyll leave some liquid in the bag when i thaw it.
ive heard of some birds that only like food at certain temps, my bird doesnt seem to be one of those so i havent had to heat much of anything for him, i guess thats what makes my 'technique' work for us
i hope some of that was helpful!
