My roo is about the same age as all his hens, as they all came in the same shipment in Sept. I've noticed some henpecking in the past (and discouraged it with Vick's and cayenne) and last night I noticed that they've pecked him on his left side so much that I can see his underlying wing structure--feathers gone--in an area circular size of about a tennis ball! This morning I walked into coop and Earl the roo was sitting in one of the nesting boxes. This can't be good.... I spread some Vicks with a bit of cayenne pepper mixed in it on the affected area to deter the biddy or biddies that are doing this. Poor Earl! I'm already treating him for a bit of frostbite on the comb...I remove him from the flock to apply the creams and the vick's and then return him so they don't see it and try to interfere...Thanks ahead for your input!
