Cayenne to keep squirrels away?

[The Luggage]

I think squirrels (or something other than my hens) are helping themselves to my girls' food. There is no way for me to squirrel-proof their enclosure, and shooting them is not a viable option where I live. I know that sometimes bird food and suet are mixed with hot pepper to discourage squirrels, because birds don't have saliva which is required to sense the heat. Do you think this might be an option for my chicken food? Will it affect the taste of the eggs? I mean, I like spicy food, but a cayenne-flavored pound cake doesn't sound so good!
