I have had chickens try to get it off. I had a few torn comb that needed treatment and they constantly were rubbing the combs in the dirt and in the grass.I forgot to mention..... Tank my hen who had that bad mite infestation last year .... Still looks great but on both sides of her vent she is still missing feathers. I decided to Nu-Stock her up again and hope that helped the feather regrowth. We the next morning her bare spots were glowing red & irritated. She hated it so much she pick & pick trying to get it all off. So I guess no more Nu-Stock for Tank. Has anyone else had this problem???
Not sure the red was from her trying to get it off..or from the product its self.
