I have 2 Reds that have been "motling" all fall or so I thought. I am now seeing they are being pecked by my Leg Horn. One Red has an open wound. I have cleaned it and both reds are wearing chicken jackets to protect their backs. The past few days I have been able to spend more time with them and just saw my Black sex link pluck a feather of a red and in 3 gulps eat it. We hand raised these 4 this past spring. Also the Leg Horn who lays daily hasn't laid in 5 days, thinking the frigid cold has something to with with the laying. They seem healthy, normal activity level, no mites, poooh isn't runny......Any suggestions please.
