When I hatched some of my own eggs a few weeks ago, I got about 20 buttons. 4 days later, 3 of the roughly 10 Coturnix eggs I put in hatched. The baby Coturnix were very small, from the very first eggs my young birds laid, and about the same size as the buttons, so I just put them all together. Now, everyone is growing, and the 3 Coturnix are starting to stand out, kind of like 3 NBA players standing in line at a movie theater with the general public. Do you think they will continue to be compatible, or will I need to separate soon for the safety of the buttons?
