I was wondering if Frontline is safe to use on chickens. If so it would treat lice and legmites very effectively.I had an outbreak of poultry lice a few weeks back and have tried everything to get rid of them. I've sprayed the chickens coop down til it was dripping and dusted all the chickens evry 7-10 days for quite a while now. Can I use Frontline on some of the chickens I won't be eating eggs from. Also, Is Ivermec a better alternative for treating them?
