I would advise an aviary size of at least 150 square feet with a covered area for some shelter and preferably some shrubs added for some extra interest. Lady Amherst's pheasants are very hardy and are easy birds to look after. Although they are likely to nibble plants in the aviary they are not as destructive as many of the other pheasants so plants are more likely to thrive in their pens. They can sometimes be housed with other birds in the same aviary although no other pheasant species should be kept with Amherst's of breeding age. Cocks of different pheasants can be together as long as no hens are kept.
