Hello! I'm a new chicken owner. My 25 White Leghorns were hatched October 4 and I have raised them since day old chicks. They are now 20 weeks old and haven't started laying yet so I was wondering if anyone had any advice on when they usually start? Or what I can do to encourage them to use the nest boxes? Right now they seem to pull all the hay out of the boxes and it's frustrating. They are all getting their red combs and "Gobbles" as I like to call them. I was told when they turn red they are ready... but so far no eggs I am still feeding them grower with some peas thrown in there and I also give them squash and other veggies and fruits every other day. Should I be feeding them layer now?
