Hi! I'm very new to this and am getting my first 3 chicks in a few days! We are planning to convert this shed into a coop. I plan to build a ladder coming down from the window leading to the run then just add a nesting area and a perch inside the shed. We will also make a few modifications to patch any holes to make it a bit more secure. My concern is that this she's is made of metal and siding. I don't seem to see other coops made out of this so I'm wondering if there is a reason! Any input would be greatly appreciated and welcomed! These will be true backyard chickens as we are smack in the middle of the city in a neighborhood!
