1. Do they like to roost high off the ground? 2.What bird size do you compare them to...a pigeon, wild mallard, dove? I've seen weight but not size. 3. I have a large outdoor/indoor aviary that I bought the plans for and built a long time ago and wondered if they could be kept in it as it is taller than wide. It has a wire floor with a removable tray. The size is around the size of a love seat but 6 ft high. *No measurements on me). 4. I'm thinking of just two chickens here a hen and rooster. 5.Any other breed that would be small and would do well in a cage like this?
