Whenever hes on a brick (We put some pricks in the coop so they can rest on them) and gets scared, he falls right off, falls on his wing, and scatters everywhere. Hes very sleepy during the day, too.2 Days ago he slept under the coop house and I think something bit him, but if something did bote him, there would be bite marks on it. Do you think he has a cold? Sickness? Please help, this is one of Princess's (Tiny's hen) first batch.
