I'm building my first coop!!! The girls should be ready to go out in it about 4 weeks from now. I'm doing a 4 x 8 raised 32 inches off the ground. I'm going to do a lean to type roof (easier for me to build) and am trying to decide how high the roof should be to give the girls room to roost. Is there a "typical" height. How high off the floor should their roost be and how much head room should they have above when sitting on the roost? It's really cool building my first coop. I trying to repurpose as much as possible. I'm using some PT wood for the base that was laying around the yard from my raised garden boxes. I'm also tearing down a old shed to use the wood and the corrugate metal roof. Hoping to keep costs down. Praying it doesn't look too ghetto!
