Hi all! I have a group of a dozen EE's that are 5 weeks old. They've been out of the brooder in the coop area for 2 weeks now and not under any heat. (We're in Texas). Wondering when I can start letting them free range in our 1.2 acre yard? They seem so young, although they're fully feathered. I was planning on releasing them maybe 2-3 hours before dusk and then going out at dusk n being sure they were all in the coop. Good idea or no?
