4 weeks old, we have only our list from MMcMurry Hatchery to go by, and all your BYC expert advice and pictures to guess what our 26 chicks are. One of these chicks is really aggressive. It relentlessly pecks at all the other birds. We are handling it a lot, but as soon as we put it back it starts up again. We read on the site that this breed can be cannibalistic, that is one of the reasons we think it is a Cornish. Any ideas? All of the birds are in large boxes in our living room (chicken village) waiting for the weather to get warmer, so we can keep a good eye on the situation. We are a little worried once we are able to put it in the coop.
