I am a college student who studies three hours away from home, so I don't go home often. My dad has been taking care of my flock of two roosters and seven hens but apparently didn't ever check for parasites. I came home for Christmas to discover three huge problems: my coop was infected with red mite, ALL of my chickens have what I think are poultry lice (little white crawlies with egg clusters around feathers), and one poor pullet has horrible scaly leg mites, to the point where some of her scales are falling off. I have scoured and dusted the coop with DE and another insecticide, and it has recently snowed. I don't see any signs of red mite, but doubt they were that easy to get rid of. I have been treating all the birds with Poultry Protector, spraying them to try to get rid of the lice. I have used a toothbrush and Vasline on my pullet with leg mites, but don't know how much it is helping. Is there anything I can do to kill off all the pests quickly? I have to go back to school soon and don't trust that my dad will be able to continue treatment.
