laying or not?

[supercow69]

I know my chickens started squatting when they started laying, however my question is if they are not squatting are they off lay? They are not pullets they are mostly around 3 yr olds and layer kind of chickens (leghorns, red star, black star, Americaunas, rhode islands and barred rocks)If a chicken isn't squatting is she laying or not if she's already a mature layer?
