Hi there! Yesterday I brought home 3 canaries (a hen, buttercup and two cocks, prince and chase) for breeding. I still need to get another hen, but thats besides the point. Yesterday all 3 were happily flying around my aviary, all very active and seemingly healthy. This morning I went into the aviary and I noticed what looked like a really big poo. I ignored it and just thought one of them had gone to the bathroom this morning after sleeping all night. I decided to give it a closer look and I realized that there were shells all around it and that there was a burst yolk in the middle. I called my dad (an experienced breeder) and he told me to put buttercup and either of the cocks into the breeding unit we have inside the aviary. (Buttercup was on her own when we bought her yesterday, so if she is pregnant then it would be from a bird from her old home) We managed to get her and chase into the breeding unit, but am I doing the right thing? She didnt built a nest for the egg we lost, but this morning she was sitting quietly with all her feathers puffed out while the others flew around and sang. I know that the hens sometimes lay clutches without having mated with anyone, but to have her lay eggs less than 24 hours after coming home.. I just don't know what to do. I feel bad for having the two in the breeding unit because its so small compared to the aviary, and now prince is all alone. Does anyone know what I should do?
