There is SO much conflicting information, I am confused at this point. Currently I use food grade DE in the coop and on the roosts. My lady's waddles are turning dingy grey and I assume this is some type of mite...per what I have read. They were wormed sort of blindly (splash of fellow chicken friend's liquid wormer in the water) when they were around 2-3 months old. Currently they are now 6 months and began laying. They are free range chickens. I saw ivermectin is commonly used but read the lice/mice treatment isn't for chicken lice, but cow lice. I see a lot of people use Seven Dust but I have bee hives setup 10 feet from the coop. I can't risk the life of my bees! I have also found using pyrethrum in the coop but not on the chickens. Can someone please tell me the safest way to treat for mites/lice and worm the chickens within close range of bee hives?
