So, my friend, the owner of the chicken was at school and she found children beating up on Magnus, this chicken here: Is it male or female? And what breed. I was thinking catalana, but BYC said that they were rare to North America, and we live in California. Is he/she even fully grown? Unfortunately, Maggie, does not get along so well with Ellie and Peep, the other two chickens that she got through her little brother's first grade experiment. They are larger, and potentially older than Magnus, so we don't know what to do. Here is one, we think it is a rooster: Here is the other, pretty sure it's a hen: Ellie and Peep are inseparable. The one we assume to be a Hen, named Peep, is perfectly fine with Magnus, however, the assumed Rooster, will peck him on his back. Right between his two wings, and tries to pluck feathers. Is this a dominance battle, or is it deadly aggression? Should we just let them have at it? Or separate them? What should we do?
