The little ones are easy to care for, they get same leftovers as chickens. Food is game bird food as they need at least 20% protein. And they need grit. You can make your own by smashing rocks or buy chick grit.
I could have gotten the bigger dual purpose quail, but I don't process my own meatz.
Most people get the button quail to live in the avarys and extra large bird cages to eat the spilled seeds. They don't perch as they are ground dwellers. A long wide cage is more for them since they live on the ground. And once you pair them you can't add more as they will kill the newcomers. I learned a lot in the past day about them lol
