First of all "HI" I am a newbie. I purchased six Quail from a breeder at a bird fair this past weekend. I received three Buttons and three Coturnix. The only reason I know that is from this forum. Anyway, they are the same age, but of course different sizes. I was told they are between four and six weeks old. Can they be kept together in the same pen? I have an outdoor aviary that houses 30 parakeets. It is five foot wide by seven foot long and seven foot tall.
