I assume you guys are talking about Japanese quail. The trick with the water dish is to use apiece of aviary wire over the top. Easy to take off and replace when cleaning water dishes. You can also make up water dispensers with a 2L softdrink bottle and a wooden frame strap tohold the bottle. Just like the budgie cage water feeder.
King Quail are even easier but much, much smaller. The hen willsit on up to around twenty eggs - her own or those of otheer females as well. She doesn't start brooding until the last one is laid so they all hatch around the same time. The young are so small they will go straight through normal avairy wire. So you either need a barrier around the botom five cms or use a legth of mouse wire to make a brooding pen around the nest and mum,with access to food and water.
Cats on the avairy roof at night can frighten the quail and cause them to fly into the wire and damage or kill themselves. There are plenty of threads on getting rid of cats if they do present a problem.
