Other birds living with quail? - Page 3
I know there are some people telling you otherwise, but I have successfully kept pheasants, quail, chickens, and waterfowl all together. If you place them in a small pen together, then expect much conflict. But if you have a huge aviary or dedicated space, then you could be ok. It also is species-specific. Some pheasants and quail are super aggressive and should be kept alone regardless of how nice of a palace you build for them.
Do you know which birds you plan on putting together?
