I used rooster booster pick no more a few years ago - I put it on feathers vs bare skin. I don't know if it was the taste or the smell, but the picking stopped. However, it did wear off and picking resumed. I decided to put up with the feather mess - I have three hens that look like they got a bad perm because their back feathers have been snipped/bit in half. These are hens that were raised by a guy in a bedroom for a year....their astrolorp sisters raised with them are the ones that eat the feathers. I think it was probably boredom in the bedroom (now that doesn't sound right) that started the habit.
Anyway, no one showed any ill effects from the pick no more lotion.
