My next door neighbor gets their yard fogged/sprayed by a pest control company once a month for tick control. I am a new chicken owner and our coop is close to the property line. Will this fog be dangerous to my chickens? We haven't moved the chickens outside yet since they just turned 5 weeks old and it is still a bit chilly outside, so I want to make sure that once they do go outside that they won't be harmed by the spraying.
