My chicks finally arrived! 5 ladies of different breeds plus a packing peanut. They went right into the brooder till I got off work. Now my gold laced wyandotte chick is acting almost like a rooster guarding the door and chasing any hands to nip at that come through said door (converted dog kennel). Is this just breed characteristic to be protective? We're a tad concerned it is so aggressive for a 3 day old chick!
