I have 2- 17 week olds that we have had since a few days old. They stayed in a grow out coop from about 5 weeks to 15 weeks. they always slept on the ground. roosts were provided there, but chose not to use. Also have 2- 8 week olds that we got at 6 weeks, they went straight to the new coop. DH and I built the new hen coop 4x4 that is inside a 10x10 totally enclosed run. So, all 4 have been are now in the new coop/run x2 weeks now. None of them sleep inside the coop. They roost on the support boards under it. WHY won't they go into the coop? I have gone out and put them to bed 4 nights in a row. They still won't go in. COULD the ladder be too steep? I will add a few pics.
