Hi, my 6 year old Columbian Wyandotte roo has a really bad infestation of what I think are lice. After I picked him up this morning I noticed he seemed to weigh a bit less than normal and his breastbone seemed on the barer side(flesh wise). I thought for a second that he might have mites so I checked his feathers and was horrified by what I saw..Tons of little bugs crawling all over him! I guess they're actually "lice" and not mites; they're pretty easy to see, a very light brown/tanish color, and move quite quickly. He can hardly stand or walk. I feel just awful that I didn't notice the lice sooner. I know you can treat with Sevin Dust, but I'm not 100% sure how to dust him correctly so that it removes all or most of the lice. Also, how fast does this work? Within a couple hours? Should I bathe him in warm soapy water or warm water with olive oil or something in it to smother the lice? I need to get them off him ASAP, as there are LOTS of them. It's been rainy and wet here so there really are no good dust bathing holes for my chickens to use . I have a dust box inside the coop but it's running out of dirt. When I refill it should I add Sevin Dust to it? How much should I add? Would DE work as well, or should I just use the Sevin Dust for now? Thanks very much.
