I dont understand guineas very well I guess. I have 5 I think there are 4 hens and one cock but I cannot be sure. They have finally started laying and it appears that most eggs are not fertile. I have broken quite a few and no bullseye. There is one female that has a bad foot problem and I will likely cull her. It seems that she is the one mated with the cock. If I cull her will he breed the rest or do they pretty much mate up and you need one to one. I did test incubate one of her eggs and it is developing. Darn birds.
