I have both Button Quail and Coturnix Quail. I think over all I like the Coturnix Quail, they are naturally tame and not as flighty as my Button Quail. They are round about the same as for raising. The Buttons are very tiny and require very small wiring. The Coturnix are a dual purpose bird, pretty, egg production and meat product. They lay ALOT of eggs, my kids LOVE the bite sized hard boiled eggs and do not choke on the huge yokes like a chicken egg. They are often pickled too, we have not tried that yet, they are hardy in the winter, we have got down to the teens here at night and I have no lamps on my coturnix, I do on my Buttons and you sure can tell when they are getting to cold. The buttons are super small and cute, they lay the smallest eggs and when hatched they are as small as a bumble bee or as big as a herseys kiss. They are SOO adorable!
I will be raising a couple different Bob Whites also this year.
Mainly, chicks you will need to grind the food up smaller for them and provide them a quail water or small water they WILL drown, we place marbles in our water so they can not drown or get soaked.
Some people use medicated chicken starter, but others swear by game bird starter, they swear that they loose more on chicken starter, the game bird is not medicated. I have not noticed a difference, and mainly feed the game bird starter. I wean my quail at about 4 weeks to water bottles, the ones used for rabbits or rodents, less mess, cleaner, and lasts a bit longer between changing.
Button quail should not be raised on wire floors, Coturnix are ok with it, there feet are bigger, if you do not have a large enough avary, button quail WILL fight, make sure to have a padded roof for your botton quail, they LOVE to boink and will kill themselves this way.
This should get you started!
