My chicks are about 4 months old and have been out in their coop for about two of those months. They go out to free-range (in a large fenced area) during the day and then go back into the coop at night all on their own. We go close the coop door when it gets dark, and open it back up and let them out again every morning. Sunday morning we noticed that a couple of chickens were running around in the fenced area before wed been out to open up the coop. We thought maybe theyd been hiding under the chicken coop the night before, because we didnt see them outside at all. Last night, we happened to be outside at dusk, and found out where theyd slept in the trees! We watched as Kudzu (an Araucana girl) flew up onto the lowest branch of a sweetgum and perched about 7 feet up. She was followed shortly thereafter by Shakespeare, our Barred Rock cockerel. Kudzu then proceeded to a higher branch, and then an even higher one, until she was up about 12 feet. Tonight they are both out there again, plus Magpie, a little Barred Rock pullet. They seem happy, and it's a beautiful moonlit night, so I can't really blame them for wanting to be out there. However, I know we have predators, including coyotes, because I lost two of my Cornish Xs that way before the coop was built. Is it safe for chickens to roost in trees? If not, is there any practical way to get them to come down and go into the coop?
