Yes, the coop has a solid floor. It's built just like a house. Below the coop, buried in the dirt and attached to the base is 1" x 2" welded steel wire. This baby is predator proof!!!!! I also plan on putting a 3' wide swath of buried 1/2" hardware cloth around the entire perimeter of the run just to discourage any digging.
These chickens will not be living in the coop or run, but free ranged. I did a thorough search on this site (and other on-line sources) before I started and found several comments to support that 1.5 sq ft per bird is sufficient for nights in the coop. I've heard others say it isn't, but if I'm incorrect, I'll sell this one and build another. No big deal. There are six nesting boxes and plenty of roosts. I don't remember the exact number of inches required for each bird at roost, but I provided what was recommended. And I'm putting roosts out in the run for those birds that prefer to roost outside. I ordered 25 birds (they shipped 26) because that was the minimum the hatchery would ship. I figured I'd lose some before maturity (I've lost 3 already) I live on 6 acres, but two sides of my property are up against a State Park and all of it's wildlife. (Coyote, Bobcat, Raccoon, Possum, Owls, Hawks and lastly neighborhood dogs.) I figure while free ranging I'll lose more.............at least until they become pretty savvy as to the dangers. So I'm not too worried about my being overcrowded. If it turns out they are, I can eat some, give some away, or build an addition or a completely new coop.
