I got a couple of day old chicks about 3-4 weeka ago. I seem to have a problem with one black araucana chick. It chases the other chicks and jumps on them and stomps them with it's feet. I also pecks them pretty hard. This does not look like "play" to me but more like a bird that would hurt somebody if he/she were only big enough. Anyone else have experience with an overly agressive chick and any suggestions?
