Forgive I am new to being a mom of my chicken girls. My girls are 16 weeks old and I have the nest boxes built = should I put them into the coop? I have heard mixed reviews. My boxes are 12x12x12. Yes, I was told I should not put them into the coop too early. How do you know the right time? I am noticing one of my girls making her own nest in the straw on the floor of the coop. Even today when I tried to let them out of the coop she really did not want to come out. Any advise would be appreciated. Thanks.
