Neighbor free range chickens eating where they poop

[Fancy Favie]

My neighbor has free range chickens and they often come over to the area at my house where I have several bird feeders and I have put out cracked corn for some of the larger birds. I don't mind them coming to visit and eating the corn, but they also poop where they eat and then scratch it around while getting to the corn and dropped seed from the feeders. Is it safe for them to eat where they poop?

I allow my neighbors chickens to come over and free range in my yard until they did the same exact thing. I politely asked them if they could keep them penned up in their run for awhile until the grass grows back. As for the birdfeeder problem, I just put up some fencing around my feeders. It works out on many levels; it not only keeps the chickens out but also the pesky wild rabbits that like to gobble it up as well. I also put their chickens to work for me in the garden
