He wants to know if we can use a lice shampoo for people on a chicken. Our silkie is completely covered with lice and she is going to infect out whole flock unless we can kill the lice and their eggs. For about 2 months now I've been trying sevin dust, poultry dust, sevin spray, warm baths, everything except lice shampoo. At first it didn't look so bad so I continued with the dust and sprayed down the coop and roosts every other week. I just checked her out and oh boy... They are crawling all over her face and vent and neck and oh em gee! The egg clumps are on the base of every feather, her vent area has HUGE egg clumps and I picked at some and the feathers came right out with the egg clumps. She has really dry skin and her fluff looks dusty and unhealthy. Awhile ago my mom bought Hartz Flea and Tick Shampoo for dogs but I wasn't too sure about using it. How about human lice shampoo? I told my dad about Adam's Flea and Tick shampoo but my dad said that we don't need to buy it because we can use the Hartz one or the people kind. Any help would be highly appreciated!
