I have a good size coop with some hens and a rooster inside. I also let them "free range" in the afternoon for 2 or 3 hours whenever I can. I have some chicks that are currently living in my basement with a heat lamp. My hens and roostrer inside the coop are pecking CONSTANTLY! (I recently got new hens). I was wondering when I should move the chicks into the coop with the other chickens. They would be with them at night and during the day. They would also be eating the same food. So, when should I be able to move my chicks into the coop with the other chickens where they would not get hurt by the other chickens and be able to survive off the heat lamp and eat adult food?
