If rats might be a problem I'd have cages raised off the ground. When I had quail on the ground I had rats digging underneath and grabbing them through the wire, as well as chewing their way through very thick wood to gain access into the cage to eat my quail. They even chewed and broke some of the galvanised wire trying to get in. Rats are the only predator I have to worry about but I never had any trouble with them trying to get my birds in elevated cages with solid floors. If you have raccoons about might they try to pull the quail through the wire? I have no experience with raccoons but just putting it out there.
One thing with wire flooring is that if you don't keep it clean enough the poop can catch on the wire and form sharp bits that then cause bumblefoot.
My quail love being in my big aviary which has a thick, solid, elevated, wooden base so no rats can dig in. I have multiple boys living together no problem along with the hens but my birds have been selectively bred by me for quite a few generations to be very docile so it depends on your birds. Temperament is definitely hereditary.
Hens enjoy having a secluded spot to lay their eggs so if you provided them with a quiet, sheltered corner they would likely lay the majority of their eggs there. You could plant it up to provide them with lots of shade and if you enjoy interacting with your birds it is easier in a larger space. Ours are constantly picked up by our kids and they are very tolerant.
When you incubate make sure to keep an eye on your air cells. They are your best indicator as to whether you've got your humidity right. Use a chicken egg air cell chart (search google images) but the days you'd expect them to be at the 3 stages would be days 5, 10 and 15. I go against the grain and incubate with a very high humidity, but that's because in summer the humidity can be 80%+ where I am, so the eggs seem to be set up for that.
