i raise Coturnix.
I put them outside as soon as they can get out of a brooder b/c as cute as they can be ,they STINK!
i keep mine in pens that are covered in 1/2 inch hardware cloth. 1 inch or larger is too big a hole and you WILL lose birds to predators if you use it. They do best off ground. when planning the cage size ,figure 1 sq.ft. of space for each adult bird.
Coturnix and all quail need a high protein diet of 25-30% .They also have to be protected from chickens who may be carriers of diseases that quail are not immune to such as coryza and CRD .
they require 12-14 hours of light a day to keep them laying but with sufficient light they'll lay an egg a day except when in moult 1 or 2 times a year.
Although we do eat some of the Cots ,mostly they are for eggs here. the eggs can be used any way you can use chicken eggs it just takes more.The eggs are cute ...

any questions you still have i'd be happy to answer
Tried to post pics but although i've been lurking on here for months ,i guess i need to have more posts first. If you want pics i can email them or PM? them to specific people ...
