Hey all, I had an issue in my flock last week with lice/mites (white and brown bugs) on just my rooster. I had just cleaned my coop the week before and put some DE on the floor plus I had dusted them all in the DE. The lice/mites almost took my loving rooster as he was weeping from his mouth and eye. My rooster was covered with these white and brown lice/mites so bad, I felt so bad that I never saw the signs of this before it got this far out of control. I figured the lice/mites were draining him to the point he ended up with a respitory infection, so I started my flock on duramycin. I found that for a live infestation people use "horse lice dusterIII" by me, so I bought some and dusted him in a pillow case and a few hours later they were dead. My question is how does one bird in a flock of 20 end up with lice/mites so bad it almost killed him? We did treat the whole flock for lice/mites and on duramycin. I put my roo on the duramycin liquid for three days and treated the water for the flock. So any help would be great. We have had him since the end of Sept and we kept him seperate from the original flock for about a two week period before introducing him to his flock.
