I recently moved my chickens to another location on my property. I went to go check my chickens one day and found that they are losing feathers and there are gnarly wounds and they are pecking at each other and at themselves it’s not molting season. What could this be and how would I go about dealing with it there’s no evidence of anything getting in to attack. I also have eight Rhode Island reds right next-door and another cage the same size and they are all fine. Thank you in advance for the help.
