I spent 9 hours 2 days ago bathing and dusting them, I am going to dust them all again tomorrow, I think they might be gone. Not to jinx myself or anything.....
Well, I think and hope they are gone. The morning after dusting them all, I did not see a single louse, then yesterday I checked 10 hens and saw a total of 5 lice, so the population of them has drastically decreased, and I am hoping it will completely disappear if I can just keep DE in the dust bathing area. I like your thread! It is a good idea.
