Every flock seems to have at least one chicken who cannot mind her own beak.
Old MacDonald's® Stop That Peckin'™ is a non-toxic, weather-resistant spray that helps discourage feather picking and pecking in chickens and other poultry. Hot pepper and bittering ingredients make treated feathers taste terrible, helping break the picking habit before the targeted bird ends up with raw, exposed skin.
It's also handy when introducing new birds to the flock, when everybody suddenly decides the new girl's feathers require a thorough inspection.
Oleoresin capsicum, capsaidine, and bitter agents.
Sometimes you have to address the root cause.
Sometimes you also have to make somebody's butt feathers taste awful.
Chicken keeping is versatile like that.
Shake well and set the nozzle to spray. Apply a small amount to the feathers, beginning at the tail and working up the back toward the neck.
Apply to feathers only. Avoid skin, especially areas that are already red or raw, as well as the head, comb, wattles, eyes, and mucous membranes.
Reapply as directed while working to correct whatever is causing the picking. Persistent feather picking can be related to flock dynamics, crowding, nutrition, parasites, injuries, or other management issues, so don't rely on the spray without looking for the reason behind the behavior.
