My Silkie Hen (Diamond) hatched out 5 chicks on June 6th, She started back to laying again and I found her today with 14 of her own eggs under her she has been sitting for 3 days, Ive only seen her out for a few minutes each day, I went to get what few eggs I thought she had in there out and give her some fertile eggs from some of my EE hens. Turns out she had collected and was sitting on 14 I got them out and started to take them away and decided to check them and they appear fertile, with bullseye rings and very faint pink streaks at least the two I opened.' not sure of the rest, I know for a fact that she has not been bred in atleast 11 weeks, and she has only been with Zues ( Orpington Roo), and only when I was out side and her own 2 12week old sons. and I was out with them the whole time with her and Zues and I did not see him mount her, I did see him dancing and romancing her. LOL So how is this even possible? I thought the sperm would only last or fertilize eggs for about 2-3 weeks? It is possible that she was bred just before she hatched out her own chicks and I took her out and put her in the broody pen. Would the sperm have lasted that long since she was not laying at that point so that this batch of eggs could be fertilized?? Please help, Thanks Sandy. PS I did see one of the Sons Dancing around his sister but it seems sooo early for actual breeding? And the girls are not laying yet.
