-Yesterday we had a freak snow storm and the poor rooster was outside looking like a drowned rat. I was finally able to treat the rooster in a soap bath followed by a vinegar bath. I gave him a bath in warm water with a combination of Dr. Bronner's lavender castille soap and 7th Gen dish liquid. Soaked him in there for ~7 minutes. Then rinsed for ~ 5 minutes him in water mixed with raw apple cider vinegar. I was able to see the dead lice floating in the water.
We had an unusual (for us) 6 inches of snow yesterday (we live in the desert of southen New Mexico, so that much snow is quite a rarity). The temperatures were so cold that I really wanted to get the rooster back with the flock to keep him warm (as it was 14 degrees F this morning). So after his bath yesterday, I used a blow dryer to dry him off. (In case anyone wants to know, it takes 40 minutes to fully blow dry a rooster with his winter feathers on!!) During the very lengthy process of drying him, I was able to inspect the rooster very well. No sign of lice eggs anywhere. His skin did look somewhat irritated, but no more lice were present after the bath.
