Hello
I need some advise on my canaries please. Last year they successfully reared 4 nests, totalling in 10 babies. it was all going like clockwork. They are outside in a large aviary, and this was their first breeding season together, as I have only just started up.
At the end of the season and because my female canary was still wanting to breed, I separated the male into another part of my Aviary which I had built on especially for him.
When I put the male back in the Aviary this year at the start of the season, they have carried on to have 5 nests all with 3 eggs, but none of them are fertile.
The 2 Birds get on very well, and he was feeding her while on the nest.
Is this normal please? I don't know which bird isn't fertile anymore, so
I thought I would get another female canary, at the end of the season.

Please could you tell me when would be the best time to add a female, either now or early next year.
I will be putting the male back into his side of the Aviary very soon.
Thank you

Milliemoo,

If the female lays eggs, she is most likely not the problem. Although there could be an internal problem with her, too.

Some breeders give the male a little extra vitamin E before / during the breeding season.

Do you manage the day length, so they have a fall and winter period where the day light gets shorter; and then a spring where the day light gets longer?

Are they in a mixed aviary? Sometimes another (jealous?) bird will disrupt the male as he treads the female.

I'm sure there are a lot of other possible causes.
