I only have two chickens as two of them died when they were young, all has been fine but with in the last month one of them has been going after the other. To the point where all we see is white feathers our leghorn is on the loosing end of the fight. They seem to only be fighting during the day. Yesterday we noticed that the leghorn had her tail feathers plucked out. We are not really set up to separate them but we do not know what to do. Would it help to get a few more, also they have both stopped laying eggs. The leghorn was going thru a brooding faze to the point where she was not eating so we took the box out . I just do not know what to do I do not want the other one to kill her.
