I have some 7 week old chicks in a pen and want to know if you think it is ok to free range them. I free range my hens, only in the afternoon before the sun goes down and only when I'm supervising. Do you think at this age, I can do this with the chicks - without letting the hens out too of course? Do you think the chicks will go back in on their own when the sun goes down? They do know how to roost and it is super cute to see them all lined up on the roost at night. Thanks for the help!
