Hi, I am new to the world of chickens... I have 9 golden comet pullets & have been putting them outside in nice weather(southern Maine), in a wire dog crate. Today one of them has been pecked, with broken blood feathers on the tail. I did a search & found advice of using a red light bulb, blu-kote(which I don't have) and/or duct tape. I put some corn starch on the feathers although they really weren't bleeding much. Should I pull out the broken feathers? The chicks are only under a light at night, in the garage. Are they old enough to leave the light off so they can't see to peck at her? They are getting pretty well feathered, & at least some of them don't appear to be staying under the light much, if at all. They are eating chick starter, should I be giving them something more?
