I was looking at the high quality plumage supplement and the kickin chicken spray and the electrolytes. Are all of these supplements worth it or necessary?
Maybe if the chicken was extra small, or getting a little sickly... otherwise, I wouldn't think so.
Just dig around in your cabinets and get your chicken treats from there. Their regular old crumbles, starter food and what have you should make up a large part of their diet. Most chickens will forage on their own for bugs and things like that, if given the chance.
