Reason why pheasants aren't to be kept with chickens is due to black head disease. The chickens can be carriers but turkeys, peafowl, and pheasants are more susceptible. Also worm the pheasants with safeguard goat dewormer. You can use this for chickens too, but many people use Wazine. You could go a long time or never have a problem with disease transfer from chicken to pheasant or peafowl, but it is an extra precaution against it to keep them separate, not due to demeanor of the birds (most chickens, peafowl, ducks, pheasants).

Glad your not mating all the pheasants together and breeding for sale. Amherst and RGP will mate if confined together. This has been a problem for the RGP because it is very difficult to get a 100% true blood RGP due to Amherst interbreeding. The birds are great for just keeping as eye candy, can't you agree? Bet you have a beautiful grouping of colors with all those pretty birds in your list. Been wanting some mandarins.
