It's definitely not big enough for 5 chickens. I have 2 Silkies in this coop and it's barely big enough for them.  The main door opens nice but you can't reach into the back under the egg layer so the food and water have to go next to the door/ramp giving the chickens less space to move.  I have to move all the locks as they were not secure in the pre-screwed holes. I also had to place a heavy brick on top of the egg layer hatch because there is no lock and predictors can easily open it. I have videos of raccoons trying to get into the  coop and the first place they try is the egg hatch.  We are adding a lock to the egg hatch and expanding the coop with a run because it's way too small for my 2 chickens.
