I have 24 hens and 2 rooster and for the last month i let them go as they please. I keep the door to the run open 24/7 now. 1/2 sleep outside in the run and 1/2 in the coop. They are in about a 1/2 acre area thats fenced with goat fence. There are 2 large great pyrenees in with them. Anyone think predators will get them? The dogs are pretty protective.
