I've been checking this hen as I've been syringe feeding her, trying to keep her off death's doorstep, and today I saw tiny light brownish things running through her feathers on her side, wing and back. Is Sevin dust OK to bag-dust her, as I think a bath at this point might chill her and finish her off? As others have suggested, her emaciated condition might be due to these bloodsuckers and now we know they're on her. ALSO she is in my house because I didn't want her near my birds- I'm afraid they may spread.
