Me! We had 6 for our little aviary - the plan was to have them to eat fallen seed and provide eggs and be cosseted by the kids.
It's been a mixed experience. Like you, we got them at 2 weeks old and kept them inside until they were 5 weeks and needing more space. That was great.
They are cute, lay well, don't mind being handled (not keen on it, but will tolerate it) - but, one of them turned out to be male - and was really aggressive when doing what he needs to do. So, the females were plucked and bleeding, and the quails will peck at blood - so, we landed up with a busy hospital cage. I believe they will cannibalise each other, so you need to watch for wounds.
Also had a couple of issues with prolapse and egg binding. So, that was my first experience of dispatching a bird. And, whilst I was feeling brave, I wrung the next of Chris Brown as I was fed up of him bothering my Rhiannas.
Didn't eat them, that'd be the next step of bravery for me - gave them to a bloke who keeps hawks and he used them for training the owls, which was pretty cool.
The bloke we got htem from says he keeps 1 male to 20 females.
These are coturnix quails - lay daily, some of them lay twice. The eggs are yum, a big yolk and are the equivalent to a quarter of a hens egg. Handy for packed lunch boxes.
I'm tempted to get some fertilised eggs and hatch them and dispatch the males. Or, I might just get a couple of bantams, they'd be less skittish for the kids to handle. Not sure.
However, from my experience and what I've read - they are super hardy wee things. As long as they are dry, they are fine - and they don't roost so you need to have a ground level shelter with some bedding in it.
Oh, and also, they are not bright. Really, really dim.
