I have a coop with 8 female coturnix that are about 8 weeks old. The Coop is big enough for 10-12 birds, going by the 1 sq foot per bird rule. It has a "downstairs" and ramp leading to an "indoor-upstairs" section and all birds have access to it all. Would I be able to add 2 - 4 button quail to my collection? Also, i'm assuming that an all-female hutch would tend to be more peaceful, given my (limited!) experience with coturnix. Is this true for buttons? Thanks!
