He's not too young but might not be quite mature yet.He is 7 months old. Our coop is 8x8 and the roosting bar goes all the way across so it’s 8 feet long. 6 hens and one rooster.
How old are your hens?
What kind of situation/flock did he come from?
Agrees a 2nd roost might be a good idea and space it a couple feet away from the other,
or maybe at right angles for more options.
