If at all possible, a separate individual should care for the breeder unit, and others for the rest of the farm. Lastly, domestic animals, especially poultry and gamebirds should not be allowed to mingle with the ratites. It is highly recommended to not have these animals on the farm. Poultry in particular can spread many diseases to ratites that may affect reproduction and health. Waterfowl can be carriers of avian influenza, which may prevent the grower from obtaining health certificates for the birds.
Cats can spread toxoplasmosis, a frequently incurable protozoal disease.
It is the opinion of the author that keeping these other animals constitutes unacceptable risk when raising such valuable birds. Of equal importance is the practice of regular rodent and predator control. Visitor Policy, Sale Barns, and Miscellaneous Since buying and selling these animals is important to the ratite business, a way is needed to advertise birds and get customers. One should advise all visitors that protective clothing will be provided before they can set foot on the farm. Visitors should be asked not to go near other birds before they visit.
