Hi Guys! I noticed today on of my sons roosters was a bit down and not as happy as usual. He was drinking a bit but is generally lethargic. I h gave him a once over and noticed he has mites or lice. I am just not sure which one. They looked pinkish/light reddish. They are sort of long it looked like, and the were scurrying around quickly. On the underside of his wing, it looked like clumps of crusty white stuff at the shaft of the feather. We gave him and his hens a good dusting of DE until I know how to treat this better. Any advice would be great! I don't want to lose him or his girls! Thanks in advance!!
