Well, I found out my Silver sebright, Vanilla, had eggs and adult lice all around her vent! Since she sleeps in the corner of our coop, I figured thats why. So I took her inside and washed her in warm water (it was a freezing morning, and she LOVED the bath!) then I set her in warm water, and picked as many egg sacks off as I could. Then I put DE on, and I saw all the rest of the adults that didn't drown, were running in panic. She still has a couple sacks on her, so do you think those will hatch? I've checked about 5 of my 123 chickens, and thoswe don't have Lice.
