Is she squatting? Making the egg song? Mine all, but the red star and leghorns, squatted for me a week before they started laying last year. A few of them made the egg song a few days before they layed first egg.
Yeah, that nice red comb and wattle tells you it's going to be soon though. Two of my pullets have nice redness to comb at 20 weeks old now too, yet to show any other sign.
Dont mean to sound silly but not exactly sure what squatting looks like! She will not let me near her she is a real odd ball! Dont know if it means anything but her back end seems to look quite wide now
When she walks she seems to be crouched at bit, like lower to the ground than normal!
