Egg laying

I bought a semi handled pair of Ekkies in January and placed them in an outdoor aviary. Everything is perfect and they are loving their new home. About 2 weeks after the move the hen layer 2 eggs and after 28 days I checked them and they were clear. I removed them and she went straight back down and laid an egg on the THURSDAY and a second on the Saturday. I got home from work on the WEDNESDAY to find she had laid a third. I thought I was lucky so have been waiting to candle them after 2 weeks, so I went out today (17 days) and found that she now has a 4th egg. This has only been laid in the past 3 days as I checked on the weekend and found the previous 3 are clear.
Now I know 4 eggs is highly unusual, so what is going on???
Help needed.

Are you sure this pair has laid viable eggs in the past ? ? ? How old are these birds purported to be? Some hens are prone to lay eggs without a male being present or even when the male might be shooting blanks.....

Modifying/manipulating a hen's environment can help break her interest in egg laying; removing favorite toys and/or other objects in the cage; removing any nest boxes and/or things that might be used for nesting; changing light factors, limiting light/daylight; moving the cage location.....

Since they're in an outdoor aviary, you may have to be creative if you want the egg laying to stop, but if it continues with clear/blank eggs, you probably need to split this pair up, for no other reason than to protect the hen.....whichever way you go. Since she has been laying so many eggs, you need to increase her natural calcium intake, rather than from supplements, because natural calcium is absorbed and used more readily than are supplements...scrambled eggs, cottage cheese and even the antacid tums! You also want to increase her intake of the other vitamins & minerals making sure she gets a variety of natural foods, rather than so many synthetic supplements.....

Good luck.....

Thanks Weco.
I have been assured that they are a proven pair and recent young have been sold locally. And they are about 4-5 years old.
I have had advise from other breeders that it was quite common for a pair to have up to 3-4 clutches clear after a move but the 4 eggs spaced as they are has me beat. I loved this pair so much I bought another pair 2 weeks ago and put them beside each other and wondered if the rival hen triggered the 4th egg.
Diet is not an issue as I feed the best of everything re fruit and veg and have them on tropican pellets, and boiled egg and arrowroot biscuit as an occasional sweet.

You should not have them on pellets! Their bodies don't tolerate the excess vitamins and nutrients that's being put into pellets.

A lot if breeders do lie to rid their non productive pairs. But ekkies can be hard to get them to mate. Mine lays infertile eggs and I know it's because the male doesn't know what to do.

Thanks Mikey.
The second pair I bought had a baby which I purchased also and am successfully hand raising. If my original hen continues to have issues with infertile eggs, I may play with the idea of swapping males and hope they bond, otherwise we will see what happens.
The Tropican Lifetime Granules were highly recommended to me and the are given it as a between meal treat only, and they don't seem to eat much of it. I have done quite a bit of research on pellets before giving to them and watch closely for any signs that it may have adverse effects.

You know that at Eckies are not pair bond birds, right? That males feed many females, and females entertain many males, all during the same season? It could be that she is rejecting this male but would accept the other, or that she wants both, etc. but I have to agree, most Eckies don't do well with very high percentage of pelleted diets; they are a very specialized species. Also, what sub species are they?

IF the flight cage is big enough uou could have both pairs together in the same aviary. On a research study on breeding ekkies I read some pairs will breed that way due to being around others of their kind. You could give that a try.

I read the research and was interested but unfortunately, I don't have that sort of space.
The pellets represent less than 10% of their food, most is fruit and veg and some sprouted seed. I have tried to research as much as possible and choose the best advise before trialling anything. Both of the pairs appear very happy with their partners. Both males feed the hens and groom each other. I have observed my initial pair mating and they appear to do what most books say they will do. The new pair have shown no signs of mating yet, but they have only been here 2 weeks.
I just have not read anywhere about a hen having 4 eggs or why the last appeared so late. I can only put it down to the new pair arriving on the scene and it triggered maybe a jealous response from the nesting hen.

It can be a response from the other hen. Like with budgie breeding, they're colony breeders, if you have nest boxes at different levels, the higher level would have better production of healthy chicks while the lower one have a smaller batch. It's critical when breeding budgies to give them all same type of nest boxes pointing the same direction and ar the same height to make sure everyone do well.
