my hens have discovered the bird feeders near my deck and they now keep coming on the deck during their daily travels around the yard. yesterday was my last straw, i camne home from work and they were there again, and this time there was poop all over the deck. what can i do to prevent them from doing this? i know if i remove the food source ie bird feeder they would probably stop, but my girlfriend likes the wild birds. any help would be great, thanks jim
