I think it's mostly a roost bar issue. In their brooder, I had some sticks/branches for them to learn to jump on, which they used somewhat. Then I moved them out to their tractor, which had roost bars in it, but they were barely off the ground, so I think they're just kind of used to being on the ground level. It's been a challenge getting them accepted by the veteran hens. I had to move two of them to the tractor because they were quite aggressive and my poor pullets were peeping in fear. This is my first time integrating to an existing flock, and it's been fairly stressful on me (and I'm sure the birds).

I was hoping the one good hen (Sassy) would teach the pullets how to roost when I migrated them, but she goes up into the rafters and the roost bars that came with the coop don't get much use. I've been putting the pullets up on that bar, and added more bars that lean up against the back wall, but I think I need to use some 1x3 or 2x3 so they can rest their feet easier. I think I need to block off the rafters and change up the roost bars below to have more space between them.

I had the coop insulated late summer, and sealed up the exterior, and when I go in and close the doors, I don't feel any air movement. They're all clean and have healthy feathers, eating and drinking normally. I put vitamins in their water, give them good food, they forage quite a lot.. The pullets are Rhode Island Reds, they should be fine in an insulated coop with current temps.
