I think I've decided to go with Buff Orps and New Hampshire reds. From what I've read here, roosters will mate with anyone. My naive question is, if a NH red mates with a Buff hen, what will the chicks look like, grow up to be? I don't think I care about keeping the flock pure unless I'm going to get some strange looking chickens with cross breeding. I plan on letting the chickens roam free on our hobby farm. Would I keep the flock pure if I alternated letting one group roam free while keeping the other group in the run and then letting them sleep togehter at night? Or would sleeping in the same coop defeat the purpose? Or am I making life difficult and should just let them all roam together? Are these two breeds compatible and a good choice for eggs, meat and expanding my flock? Thank you for your help! This is a great site!
