I don't have alot of quail. It seems they have been in demand this year and i'm down to 4 hens and a rooster. I have 6 chicks right now that i'm keeping on the down-low and a dozen in the bator. This is my second year with quail. I keep the cortunix 4 hens to a roo. If I had another roo I would separate the hens and give each roo 2 hens. My fertility is 50% right now. Not good.
So I suggest you put a trio in separate pens. For fertility reasons.
The best water containers are the rabbit nipple bottles. They always have fresh water and can't poop in it.
I make a feder where there is little to no waste. It's made out of am empty gallon bleach jug. If you would like to see how to make one just email me and i'll send it to you.
There are other ways to avoid waste of feed. You can cut a PVC pipe in half length-wise and attach it to the ourside of your quails pens so they have to stick their heads out thru the wire to get to it. It's less likely they will be able to waste the feed.
Cortunix are grown at 7 weeks. They are ready to lay eggs at 7 weeks and they're ready to process for eating at the same age. If you wait too long the meat will be tough and tasteless. There is a great link on youtube that shows the fastest way to process a quail.
I never provided a nest box before now but they are all laying in the box now. Nobody is sitting on them but at least they're in one spot and I don't have to gather them from all over the place.
If you want eggs all winter you will need to provide them with light for 16 hours a day. You should also cover their cage with something that will keep any draft off of them and somewhat warm. They are nasty little buggars so if you bring them inside you'll have to do alot of clean up.
I've found (the hard way) that cages made out of the 1/2" wire is the best and safest to use. Any larger and critters can get their paws in and kill them. Snakes can get in and have a large meal. I know, it's happened. My cages are made of this wire on all sides. I do have some bob whites in a renovated rabbit hutch but it has the same wire on it.
I hope this helps some. I'm no pro but this works for me. I have to go to bed. I'm seeing double i'm so tired. Good night and good luck
