So as of now there isn't a problem then?At the beginning of this post they wanted to keep the chickens off their property but they didn't want to contact the owner of the chickens or build anything to keep them away.
The chickens have been exposed to a wild bird with eye Conjunctivitis, so they were worried about that.
Now they don't want to do anything about it and let it be. If the chickens remain on their land and get sick and die then so be it.
That is pretty much a summary of the problem.
