I had a beautiful bantam buff cochin. She passed at the vet yesterday from aspiration. I have 4 of her eggs sitting on my counter and I am having a friend try to incubate them. The roo I have now is only about 15 weeks old. Newest egg is about a week old. Would he have been fertile at 14 weeks of age? They free range all day and I haven't seen him mount any of the girls but I'm not there all day watching them like a hawk. Is there a possibility?
