One chicken won't roost inside coop

[aart]

If it were all the chickens or multiple numbers of chickens doing this, I could see size being a factor. But not with one lone chicken. I've seen so many posts that blame everything on the coops and the ventilation. Yes, that can be a problem but it's not the problem here. I've seen it in multiple posts here but hoped that you would look at the situation, which is an agressive rooster and a hen that is obviously getting bullied. I'm trying to figure out a solution for that. I'm not going to go out there and measure the coop and describe in detail the ventilation when I know that is not the answer.

I think I'm done here. Thanks for the non-help.

I'd start by removing one of the males.
