Quote: That's too high unless you have Guinea hens . Large fowl should not be more than 18 inches off the floor. Young chicks do fine without roosting. As young chicks, their keels are still gristle. Letting them roost a a very young age runs the risk of them resting on the breast bone and developing a crooked keel. Or spraining a ankle, breaking a leg.
I once got a trio of older Speckled Sussex from a lady who couldn't care for them any more. The one hen arrived with terribly crippled feet. It was really sad. The previous owner told me she had her roosts 5 feet off the ground for the Guinea hens. That the Sussex used the same roosts. This poor large fowl hen had injured and crippled her feet by using these high roosts. My Light Sussex don't have roosts at any age. They do just fine nestling down in the shavings to sleep.
