I am new to forum and chickens! My chicks are from McMurray Hatchery. They are just about 4 weeks old. I have moved them out to the coop and they are all happy and healthy. I am looking forward to letting them out in the yard. Do I let them out at dawn or later (because of predators?) and when will they want to get back in the coop- before dark? I know they have to stay in the coop for a few days, so they know it is "home". Any insight would be greatly appreciated! Thanks!
