My husband, without really thinking sprayed our yard with spectracide. He didn't think about the fact that we wanted to introduce them to the yard to free range since they are now big enough. He stayed away from the coop and run while spraying but I wonder now how long I have to wait before the chickens can free range again. All the FAQ's on the spectracide site just said not recommended for use with grazing animals. That's not much help. Anyone with experience with this?
