I am having a terrible time getting my girls bald spots to fill back in. The bald s[pots started with a new young rooster and were perpetuated by the hens themselves. I have had saddles on them for almost three weeks and the feathers were growing back in great under there. Once in a while when peeking to see the progress I would see a teeny tiny yellow bug on a couple of the girls. This was kind of freaking me out so I decided to take off the saddles and let them scratch and clean themselves and since the feathers were just over an inch long, hoped they would not pick at each other. I was wrong. I left them for about an hour and every single girl with new feathers (7 of them) now have complete bald spots again and one is raw and bloody. I am pretty sure it's my white leghorns as they are the only ones I see constantly pecking at the others. I have put all the saddles back on and will leave them but I am really concerned about those little bugs. Any suggestions about them or any of my dilemma would be greatly appreciated.
