We have a couple of 9 month old PR's. Laverne and Shirley, Shirley has been laying for a couple of months now. Laverne has yet to start but seems to be getting close with her pelvic bones being 2 to 3 fingers apart now and almost pliable with a big red comb. Shirley has been laying every day until about 5 days ago. She has suddenly stopped. She still has a big red comb, 3 fingers apart on her pelvic bones and very pliable. She doesn't act any differently. Doesn't seemed distressed. All of our chickens free range all day long. This week has been the coldest so far, they have seen snow for the first time yesterday and we still have it today. We do not give them extra light. We get anywhere from 5 to 7 eggs from 8 chickens that we know can lay an egg. She still eats, she is not listless or seem sick. Could it just be the weather and the lack of extra light? I just want to make sure that she might not be eggbound. What might be some signs of being eggbound that I should look for in her. She does seem to have some black spots on her comb? If needed I can take a picture of her comb. Thanks for any advice and input!
