I have a black silkie rooster, and three hens. An ameraucana, lavender orpington, and a cochin bantam. Does anyone know the possibilities of him mating with any of my hens? My ameraucana has been laying for about two months now, so I know she is ready. However, when he tries to "mount" her, most of the time she fights him off. I have seen her squat for him, but he doesn't seem to be able to "hit the right spot" for lack of better words. Also, He has had some respiratory problems the last two weeks, sneezing/coughing. I have put all four on Duramycin 10, but he has dropped some weight. I want to deworm all of them but not sure how long to wait, if I have to wait, after they finish antibiotics.
