My girls have been picking feathers, actually it's just 3 or 4 of them I see doing it. I started them on the Avia Charge 2000 and it has decreased some. I'm also trying to keep them very busy by heaping in weeds, sunflower stalks and free ranging when possible. Their coop & run is sufficient in space but has nothing left for them to graze on. I have several with bald spots on the back just in front of the tail. I've seen several posts suggesting the use of pine tar (which I have on hand for the horses) or Vick's to deter pecking. My question is whether it is safe to apply directly to the skin and will either of these products inhibit feather re-growth? There's only been a couple of occasions that the pecking was so bad there was blood and I immediately treated with Wonder Dust to dry up & coat the area. It seems the posts I've read that recommended these products was aimed at using it on their combs & wattles. With the cold weather setting in I'd like to see those areas filled in with feathers! Thanks!
