Is my hen going to lay soon?

[1sttimr]

I'm impatiently waiting for my girls to lay! This is my first flock, my oldest is 25 weeks but I think my Barred Rock, who is 20 1/2 weeks is most mature. She's grown huge comb and wattles and is the loudest of them all (and is my favorite) but isn't squatting yet. Can anyone tell by looking at her if she will lay soon? She doesn't squat, at least I don't think she does.

Squatting doesn't really have much to do with it.
Squatting comes when a pullet/hen wants to breed and there is no rooster. It's kind of like a female cat in heat.

She looks like she's close but adding light will kick them into gear.

She's close. Not all pullets will squat for you - some are less submissive. If you have a rooster in your flock, then she likely won't squat for you because she's already doing that for the rooster.
