Hi. My first flock is now 4 1/2 months old. The coop is raised and we have a nice ramp from the ground up to the landing which then leads through the door. Every evening, the hens walk up the ramp and go inside to roost. The rooster, however, won't use the ramp. He wants to jump straight to the landing. So for about 15-20 minutes, he'll pace back and forth under the ramp from one side of the landing to the other. Each time he'll look up, like he wants to jump for it but isn't sure he'll make it, and then turn and pace to the other side and repeat. Eventually, he will jump, and barely makes the landing. I've never seen him miss but suspect that it happens somewhat often. He just ignores the ramp itself. Then here's part two: Once inside, he usually will not join the hens on the roosts, but instead just sleep on the floor in the wood shavings. I used to see him on the roosting bars every night, now it's just one or two nights a week. He's a decent size bird, but I don't think he's particularly heavy or otherwise unable to reach those heights. By the way, the landing is 24" from the ground, and the roosting bars are 21" from the coop floor. If breed is a factor, I think he is a Barred Rock. If not, a Cuckoo Maran (bought one of each as chicks, and I'm not positive which is which).
