My speckled sussex hens are 19.5 weeks old. The nesting box is a kitty litter dome with artificial grass and 2 plastic eggs in it. I put it in their coop a week and a half ago and theyʻve pretty much ignored it except for sleeping wedged behind it in front of the door. They have never slept on their roost, always in a pile. This morning when I went out to let their ladder down, Clack was inside of the nesting box (I was very excited) and Cluck had her head in the door and was perched on the edge. They were like that for about an hour until I booted them out to see what was going on. I suspected Clack slept in it because there was quite a bit of poop in it. Tonight they were in the same configuration when I went out to pull the ladder up. I kicked them out of it and turned the opening towards the wall. The coop is an A frame tractor so I canʻt reach the roost to actually put them on it at night. They spend a lot of time on the roost during the day but not at night. Any suggestions?
