I have three Rhode Island Reds. They have just recently reached their maturing age. One is laying out of the three. I noticed yesterday that I have my "middle" pecking tail feathers out my last (in pecking order). My producer has nothing to do with it. I understand it's more than likely related to stress. I had a heat lamp on for them for about a week straight and recently changed their food. I unplugged the light now that its more than 25 degrees outside of St. Louis MO. Any other suggestions on how to de-stress my chickens? I dont want my middle to be bald or get picked on. TIA!
