Which is why I tore out the roosts in the hen house, I was having fits with those silkies thinking they can fly, launching themselves from 5’ up! Brats!
I'm sorry, I have Marans and Marans crosses. 6 feet is no problem for them. If they need to, 9 to 10 feet straight up they can do. If they want to go higher, they just find something to use as a ladder until they get as high as they want. Squirrel one of my bigger crosses, sleeps about 25ft off the ground in a tree beside momma hen.
This roost, is about 12 foot high, no problems. Even my silkie rooster is able to get up there by himself. Not in one leap, but he uses the stall boards like a ladder and does in in 3 hops.
