I've got four chickens -- first I got two 6 week old ameraucanas (they're more like 7-8 weeks now), and then a few days later two four month old bantam cochins. They have all been getting along just fine, no pecking or squabbling or anything. In fact, the two little ameraucanas like to snuggle and burrow underneath the cochins, and the cochins will just sit there sandwiching the ameraucanas like they're all playing house or something. One of the cochins is always the first to do things -- she walks out of the coop door first every morning, comes over to me when I offer treats first, figured out how to go up the ramp to the coop today and then called to the others that she found food (I stuck the food up there to help encourage them to figure out how to go up), and she's the only one so far to use the dust bath I made them. Is she just the smart one, or is she the boss?
