Hate to tell you this, but DE won't kill the lice. I tried it, but gave up and now I use Poultry Dust or 5% Sevin Powder. Can you get cat/kitten flea spray or powder?What I haven't thought to mention is that I've noticed she's carrying quite a heavy lice load. The other two hens have none that I can see, and the roo has some nits, but I can't see any live bugs.
At any rate,I treated them all , and the coop yesterday with DE, since apparently we can't get Sevin here without a license.
How long approximately before the DE kills the live bugs? I know I'll have to dust again in a few days to get hatched nits.
