I injured my sweet Australorp hen, Whiskey, through ignorance. The other three hens were picking on her continually, I was told to put a saddle on her to help with the pecking. Well, I apparently left the saddle on to long and all her feathers on her back and shoulder have been rubbed off as you can see in the pictures. I have put a tea tree injury oil on her back. What can I do for her? I researched the internet and there were suggestions as to mixing a high in protein feed (21% or 28% protein) with the current layer feed to help her grow the feathers back. Or will the feathers grow back when she molts. I feel so bad for her since I caused this. Any suggestions? Appreciate any help. Thank you
