Hi! I have a flock of 5 chickens. I bought all of them on a market, from different owners. One of them, a blue andalusian is supposed to be 1 year old and after we had bought her she gave us eggs almost everyday but after 1,5 weeks she stopped completely. We thought it was due to stress because she had just gotten a new home but 2 months has passed now and still no eggs!! The other 4 chickens are still too young to lay. I've also noticed that her comb has paled from blood red to this dull pinkish looking color. Also, she is the flock leader so the flock is following her all the time and whenever she finds food she always makes this weird sound and gives the food away like a rooster would do. It may sound like a silly comment, but can that have affected her egg laying? I've also noticed that they have been in the nesting boxes (all the feathers). Should I close them now when no one is laying? Would really appreciate your expertise! Thanks!
