My 20-week-old girls haven't started laying yet. I joked with my neighbor that I was going to borrow one of her older hens to teach mine what they're supposed to be doing. I was half serious. Do you suppose that pullets start laying sooner if they're exposed to more experienced hens?? Mine have never even LOOKED in the nest box. It's so HARD being a impatient, finger-drumming, control freak. I'm gonna go squat in the nest myelf.
