Hi! First time chicken keeper. I put my chicks in the coop this week. They are 6-8 weeks. It's been a bit cold (going down to 5 degrees at night) so maybe they are just getting used to it. But they are all cuddling on the floor or all piled on top of eachother in the dustbath I put in there - like the pic. There are 12 chickens in there! It's quirky and amusing but I don't want them smothered! I wondering if this is normal? How can I encourage them to roost? What height/width should the roosts be? All advice is appreciated!!
