We have 3 bantams that are almost 6 weeks old. We think at least 1, possibly 2 are roosters. Thinking about getting 2 to 3 more, in case we can't keep the roos. But they will be about 6 weeks apart. Will I have to wait til they are full grown to put together? Or if I put a cage with the young ones in the run with the older ones for a while do you think I can put them together after a couple weeks even with that kind of age difference. The older bantams are 1 cochin and we think 2 OEG's. I don't have anywhere to house extra chickens long term if we can't get them together early on. Thanks for any advice!
