How high are the perches/nest boxes?

Is there a chance that he got steped on or he broke something when coming off the perch or where he sleeps/rest in the coop?

When did you find him like this?

Have you noticed any eggs missing in the boxes?

Where do you live? Is there any chance of a snake in the coop?

On his legs are there any bumps?

If they were beating him up...I hate to say this...is he still alive?
