I would suspect that if you keep any mixed species together in close quarters there can be contamination that occurs because they are all susceptible to and carriers for different things but they are all birds and share at least some common DNA so making them capable of transmitting disease one to another. With so many varieties in close proximity the probability that something could rise up and bite one if not all increases.It could be dangerous for other poultry as pigeons can get canker (trichomoniasis) and I guess they could give that to the other poultry. In a perfect world I would have separate areas for the different species... Maybe someday, lol.
Maybe you should ask someone in the pigeon forum?

is there some lexicon of all the abbreviations you guys throw around.
