We picked up our chicks Sunday and for the most part they've been really easy. Quiet, eating well, drinking well, sleeping and playing. Growth appears normal with flight feathers starting to pop out..all is well except for one little Buff Orpington chick that loves to run around and yank at the flight feathers on all the other chicks. She's not picky about which breed she's tuggin' on, just whoever is closest will do. She's the only one of the 17 that is doing this, so is she establishing that she's the "Head Hen" and it's normal pecking order, is she a bully that is going to remain a bully and something should be done about it, or is there something else going on that I'm too new to be aware of? Appreciate some feedback!
