I have taken in a couple of roos in need of new homes and while they didn't get along with the boss roo already here, they have been great (and very happy) to run around loose in the pasture with the horses, goats and donkeys. They scratch up fresh poo and eat fly larvae (maggots). I credit them with the lower fly population this past summer. Since I love the sound of crowing, it's a win-win!
Good luck finding them homes--maybe this gives you some other options.....
