I started out with one of these. I had 6 hens at the time. They were happy in there, ventilation was actually fine, I kept both vents open all the time. Totally pred proof, I hung their feeder underneath and same, they just roosted in there. Out at dawn. Fast forward, I lost 3 to hawks and neighbors dogs. Got some more (state min of 6) so I was up to 9. That was too many for the house. I ended up getting a second one (foolish waste of $$). This caused all kinds of turf wars of who was allowed where. Fast forward again we built a walk in coop. I sold one snap lock and I use the other one for my 3 ducks.
The large snap lock is good for 6 hens. It has 3 roots bars but if all three are utilized then they poop into the nest boxes. It’s a pain in the a&& to clean. Easier for me now that it’s on the ground for the ducks. I open the roof to clean out. But when my hens were in it I used sand substrate and it was poky and difficult to clean which meant it didn’t get cleaned thoroughly as much as it should. It is not sufficient for the number of hens they advertise. The birds I had were hatchery quality Wyandotte’s and barred rocks. So not massive birds.
