Button quail are almost impossible to tame. Some people have, but it's usually a case of a lone-hatchling. I have a rat manor cage that is divided (top and bottom) for some of my buttons; top part has 2 females, 3 males; bottom has 3 females, 4 males. I have some other buttons in a rubbermaid tote, I believe it's a 105 qt. tote. The top has 2 large 'windows' covered with hardware cloth; that pen has 3 females, 5 males. You can keep a pair (male/female, male/male, female/female) in a 10-gal. fish tank, but the more space you give the better. Mine were all hatched together, so they get along pretty well. I do have a feather picker in one of my pens though, if I ever figure out which one is doing it, I will get rid of that one!
