No, not at the moment, not at this house, but I do use preventative stuff on the dogs like frontline. We used to live downtown in one of the historic neighborhoods and that house was LOADED with ticks. It took us almost a year to rid the house and yard of them. We moved in and within 2 weeks, they were literally crawling upthe walls. I was ready to move right back out and sell. My poor dog was covered and that was after a tick dip. But your chickens should at least eat them, so I've heard, and I would treat the dog monthly until you don't see them anymore. Sounds like the neighbor has a bad problem and is sending them your way.
