My first time pullets are 7 months now. I noticed the largest doing some squatting behavior 2 days ago. She now is hanging out by our front door, and she has the ground bowled out like for a dust bath. She does not want to leave. Her squatting is more frequent so I suspect she is getting ready to lay. I put a box out there with shavings and an egg from someone else. Should I move her into the coop?? I don't know if she knows where to go.
