Ok, so one of my friends just told me he has a pair of mixed pigeons I could have for school. His flock is composed of good homers and squabbers. I have never raised pigeons before and I have alot of questions so just bear with me. He's been raising pigeons for almost thirty years but he is too busy to give me much info because he works alot. 1. Can I inbreed to get a small flock from this one pair? 2. How big does a single pair pen need to be? 3. How big do my nest boxes need to be. 4. Can I feed them chicken layer feed mixed with bird seed? 5. Can they be housed with my broilers until I build a coop? Thanks. I may add more questions as I go.
