Okay, I have 7 19 week old pullets that are a mixed flock. All except my 2 BRs have large RED combs that grew in over the last couple of weeks. I am new to this, so I suspect just by age and comb maturity eggs are soon to come, but I keep looking for squatting and I just don't see it. I try to scratch their backs but most just run away; they've never been ones that like petting. I do notice A LOT of fluffing, more than usual, but can't tell of any squatting. Is it something that a trained eye would see or will I know for certain when they squat and mine just haven't done it yet?
