I wasn't sure what category to put this under. I'm having an issue with my eggs. I have a pair of Silkies that I want to breed (they are rom show quality lines, not tested though). The hen is laying and had been previously fertilized by a different chicken (over 5 weeks ago). We incubated a couple eggs and when the chicks hatched we discovered she was "with" the wrong male. So, she is now in a breeding pen with her male. About ten days ago we took all her saved eggs and threw them in the incubator. We had checked them and they appeared to have a blastoderm ("target"). Now, in the incubator, they have been candled and look like nothing is there. This isn't my first time candling, but I can clearly see now veins or dark spots. So, we candled another of her eggs yesterday and there was no blastoderm at all. Questions... Could his sperm not be reaching her? (I've heard of people clipping feathers to make sure everything gets to where it needs to). Would there be another reason why she's not being fertilized? The Roo is very confident and "manly". Loves to crow. When he was in with the LF, he loved trying to mate with them.
