Ok, so I've had chickens before but my situation is much different now. Before I had 6 free-range Buff Orpingtons on 2.5 acres. Now I'm considering 2 or 3 chickens on a large suburban lot. Before, my chickens got eaten by coyotes and cougars. Now... cats? Raccoons? So now for my questions. 1. Our backyard is totally fenced by a 5' wood fence. If I free range my chickens will they be able to get over the fence into the neighbors yards with the mean dogs? 2. Can I have 2 chickens, or would 3 be better? 3. Are there any breeds of chickens that are quieter than others? 4. Are there any real simple but attractive designs for coops/runs for 2 or 3 chickens? I could build something more complex but I have to build it fast if I want to get spring chicks this year. 5. I need to get into this for the lowest possible cost. I remember the feeders (chick and chicken) and waterer I will need, but I don't recall if we put a heat lamp or just a light in the roost? 6. Is there anything I might be forgetting?
