I recently was given some bantam Rhode Island Reds from a nice enough old guy. Now I think I know why. When I got them the rooster was covered with mites. They were bad, real bad. So I treated him and he has them no more. Anyway, the little hens kept on laying, so I decided to put some in the incubator and hatch some chicks. The eggs are at 12 days and I just threw out all of them. They were not fertile. I know the rooster is doing the deed and all. I am wondering if the mites may have reduced his fertility, or if he is just a sterile bird? Should I keep him till spring and see if his fertility rate changes? He is a year old, according to the old man.
