Have no luck searching online for pigeon raising questions. How many makes a happy pigeon? 1-5? I want 1 pen/cage sometimes 2 no more (+ a hospital suite).. Is that ok for keeping a breeding pair? What protein % do they need? Do they all fly? Some look too fancy to fly. Which birds are easy breeders, and can raise their own young, besides homers? Can all breeds be trained to come to the feed whistle? Can you recommend a link or book on basics? I've heard tumblers, rollers, and homers are the easiest. I need a smaller sized pigeon breed and I can't find any weights listed. Are they all under a pound? We handle a parlor roller and it was a great size. Thanks all so much!
