My babies are now 6 weeks old. They are well adjusted to thier coop, run, big door and little chicken door as they have been using it for a couple weeks now. I leave a light on in thier coop at night "night light". I have been trying to test them and see if they will go in at night by themselves and they NEVER do!!!! Tonight it was a lot cooler 55 degrees, so I did not chase them in but left them to see what they would do (it is even drissling out and cold!!!) I just went out there (11:00 pm) to find all of them bunched in a corner of the run "outside" sleeping!!!!!!!! Why Ohh WHY!!! are they doing this. Wouldn't, shouldn't they understand its warm inside!!!, My roost is inside, !!! I'm safer INSIDE!!!! Ohh goodness what to do what to do????????????? PLEASE SOMEONE ADVISE!!!!
