I have a big bully in there, the other 2 get whatever space she doesn’t feel like using You could house more birds if they all get along well, but certainly not what the advertise it for!You have to kneel or move it to a clean spot and then clean up the mess. It does come with trays though for the coop you just take out and dump. Super nice if you don't put them too close together. I also don't stick with the whole 10/4/1 rule people insist on though. I go off the actual birds. I have some that handle stocking rates much differently than others.
