My new chicks, all 12 of them, Been in the coop for about a little over 2 weeks. At first I was putting them on the perch at night but they would still be huddled together on the floor later. Now, it has warmed up a bit in the evenings 67... and they are being found huddled together in a corner of the run ever night, I go and put them in the coop and they act like they dont want to go inside? It is dry and nice temp inside not hot or cold just comfortable yet they stay outside? this is every night now. Im just leaving them out there as they will go right back out anyways after I go in the house. Whats the deal?
