My chickens free range all day, but I do scatter feed on the ground for them to peck and scratch at. I don't mind if a stray wild bird eats some (like we have a pair of doves that have been hanging around) but I was having a problem with my dogs eating it. They would eat all of it and the chickens wouldn't have any. I was having to feed them A LOT of feed. I decided to mix some cayenne pepper in with the feed today. The dogs tried it once and left it alone after that. I wonder why? lol I haven't had to feed the chickens nearly as much today as I normally do. I'm glad I remembered that little trick.
