I was noticing some of my birds itching themselves, and when I checked, i saw littlebugs. I'm pretty sure it's lice, and i feel awful because i just added seven more to my flock, and I don't want my new girls to get it too! (Or do they already have it?) I was in Trustworthy yesterday, and i found sevin dust, and right next to it was a smaller can, called Buhach. It even says "for lice on chickens" on the back. i got a cn of each, but i was wondering if anyone else has heard of this stuff, has it been effective? There is a website, and it says it's an all natural pesticide.
