I have a hen who is ALWAYS broody, she disappeared a few weeks ago and I found her nest yesterday full of rotten eggs. I brought her back to the coop and found her CRAWLING with lice. I dusted her completely and added her to the flock again. Tomorrow I'm going to a sale where I hope to sell her, but I don't want to infest any other birds with lice. Since I dusted her yesterday evening, will she be ok for tomorrow morning? I can dust her again today if that will help, and tomorrow morning before I leave. I'll probably dust them all before I leave just to make sure.
