I have a Cochin roo and two Silkie hens. I think he's mature since he has been trying to mate with my big girls. He falls off. It's so funny! I now have a fancy chicken run since they were standing in the rain and getting soaked. Is it hard for a little roo like that to breed with all those feathers? I put a couple eggs in the incubator that did nothing after a couple weeks. I cracked one open and it had a big white dot. I read somewhere that that means it's fertilized. Is that true? Is there any hope of getting some babies from them?
