just got six new hens to add to our three. i was just now holding one to get her accustomed to me, and to check her over. i found little light coloured, oval bugs on her, about an inch below her vent. i called the vet and he said to put sevin dust on her. i wish there was an alternative treatment, but if this is the best thing to do, i will go out to the shed and get the sevin. i strongly dislike the bad kind of bugs. i want to eliminate them now. today. i really need some advice. help. ahhhh!
