I hatched a few chicks in Feb that are now 21weeks old. I gave my dad 7 pullets and 6 of his have already started laying, a couple of them have been laying 3 weeks now. I kept 11 of the pullets and only one of my pullets are laying!! We are both feeding the same feed. The only big difference is I have a 7 month old rooster but he is wonderful with his girls and they love him. They follow him around, he protects them, keeps the peace, and also likes to find food for them. Am I doing something wrong?
