I read somewhere on this site that when you move chicks from their brooder out to their coop, that you were supposed to leave them shut in the coop for a week and that was how they learned to go back in at night. Somehow they then associated the coop with security, or home or something?? Seemed harsh when I read it - but is there something to that? - I sure don't want to be chasing chicks into the coop at night!
Well, my girls were shut in their coop for 2 weeks due to inclement weather and they sure didn't know to go back to the coop at night!!!
