I have a 13 month old blue Australorp that i have never seen near the nesting boxes. I have had her in a separate enclosure for a few days now, and it appears she is in fact not laying, and never has. It is quite hot at the moment here in southern hemisphere, but that is really old for a chicken to not have started laying! Her comb is red like the others. Should i keep waiting or is she an anomaly and might never lay??
