Hubby and I just deloused the flock with a commercial livestock powder (in-the-pantyhose-pouffy method), 14 adult birds and 2 chicks, most of them were CRAWLING with lice and I have no idea when they got infected or how - sooo gross and I feel like a bad flock mom for not noticing sooner Right after they were all done, three of the girls gave themselves deep thorough dust baths in the sandy floor of the old coop as we had opened access for the procedure (the ceiling is taller in there). My question: would they have shaken out all medicated powder we just put on them by doing this? Oh please lordy no! I also dusted the coop as best as I could but it's so big, I'm sure I didn't get everything. I emptied the nesting boxes of the hay that was there, put lots of powder down and then added fresh bedding (wood chips). I know I have to do this all over again in a week, right? The hens with denser thicker feathers seemed to have less lice, as did the silkies - or do the bugs just hide better in those birds? It's my first time with bugs and I am thoroughly disgusted. But my poor birds, how horrible for them to live with vermin like that!! PS: I ordered food-grade DE, which should arrive next week. I will sprinkle in the coop, bedding, add to their food and to their new sand box. A friend of mine is bringing me ashes to add to the dry sand and DE. What am I missing? THANK YOU!
