I know you're probably getting tired of me asking, but I really need to know. My 10 hens (2 years old) haven't laid eggs in 4 months. They suffered from mites, and we lost 3 chickens. So now, a few of the hens are getting red combs, some have pinkish combs, but my dominant hen has the palest of the combs. The hens with the red combs seem to be ready to lay, but they haven't. I was wondering if the dominant hen could be playing a role in their being no eggs, since she isn't ready to lay yet. Should I, as a precaution remove her from the flock for a while and see if that helps. Please any help will be appreciated.
