I'm new to chickens. This is my first ever flock. This whole time I've been wondering when my 2 oldest chickens are gonna lay, but after talking to others and reading what the signs were I realized my 15w Speckled Sussex has a lot of those signs. Although her comb is not completely mature and red...she is squatting like crazy, has become way more vocal than normal, has been running in and out of the coop which she has never done. I don't know...her overall behavior has changed completely. Is it possible for her to lay soon even though her comb is underdeveloped and pale?
