I have 2 different coops, this being one of them. I prefer the other (purchases through TSC, and it’s metal). I would say 4 full grown chickens are okay in this coop, but they’d need to have additional room to run. The run and the coop are fairly narrow, which isn’t my preference, but might be great for someone with less yard space.  The wood is exactly what you’d expect, flimsy. Super easy to put together but needs to sit on level ground or you’ll have trouble with the doors and latches closing properly. If you plan to use this without another run built around it, you’ll need to secure it for predators. The roost bars are a bit low for what the chickens would prefer. Easy to put together.
