Since it seems as though many of you raise pheasants I hope I can get a good answer. I have the book, Introduction To Ornamental Pheasants, and contained within are the required areas for the aviaries of certain breeds, ie 100 sq ft for red golden. In addition other sites have similar numbers, but I have yet to find if this pertains to just a single bird, a pair, or trio. I assume this is for total area for the aviary, which includes a shelter and run. Given most of the breeds raised, and those I would be interested in, are hardy, the shelter would be minimal. I have also seen birds kept in small pens where they may have only a dozen square feet for three birds. So what are the opinions of the experts out there, what size of run do these birds need, what sized shelter and any other pertinent information? I have currently a trio of Lady Amherst as well as Reeve's. I would like to get, in the future, the red and yellow golden as well as peach and dark throated red, Swinhoe, Elliot's, Impeyan and probably more but that is a start. Thanks in advance to all who help.
