Okay so I have a wild bird feeder out (that's always swamped with birds) But recently they have discovered that they can get through the chainlink of our chicken run and eat their feed and drink their water....my main question is if they will spread diseases by doing this? Should I be worried? I don't really mind them eating it, they don't eat that much. Also my hens have been cleaning up under the bird feeder where the sparrows fling the seed out since the day they started living outside and no-one's sick yet...any thoughts?
