I have a D'Uccle pullet that recently started laying eggs and I noticed today when I cracked some open that they are fertile. I was wondering if it is possible for my Orp roo to have breed her? I assumed that he was way to big but he is my only rooster in that pen and I know they are her eggs because she is the only bantam on the place. There are no little roosters here or at any neighbors that could have gotten in with her. Is this possible?
