Is there an expected time line that you see between when a pullet starts with the "submissive crouch" and first Egg? I have a flock of 22 (almost 23) week olds (Gold Sex Lin, Barred Rock, Black Australorp, and English Orp). My Barred Rock and Gold Sex link have had very red combs for 3-4 weeks and my Gold Sex Link has been crouching anytime I come near for not quite a week. Is there a way to make a guess on timing? It's been so cold I want to know whether I need to go out checking for eggs more often to prevent freezing. I am not providing extra heat or light.
