I have 22 assorted standard breed chicks that are 6 weeks old. I have them out in their coop (with a light on at night), with the deep litter method on the coop floor (it's cozy). I was wondering when I could let them range? They have been cooped up in the coop (pun intended) for a week now and they now have a friend - a 5 month old Black Austroplorp rooster named "little Jerry Seinfield" who is dying to get out for a bit of free time. The chicks were previously in my garage in a pen. So they haven't had much outside, ranging time. Would anyone be able to offer me suggestions on how to start their ranging??
