(read more here -> https://www.backyardchickens.com/forum/viewtopic.php?pid=1733607#p1733607 ) does anybody have any experience with this item from eggcartons.com? description from the web site says: A topical herbal anti-pick spray for cannibalism in poultry; formulated with all natural ingredients to help reduce feather plucking and cannibalism in birds. It contains bitter herbs and spices in a natural base. HOT-PICK comes with a finger spray applicator and should be applied as needed. 4 oz. bottle. thanks!
