Hello all! I'm making a dust bath for my chickens tomorrow. I have three babies that are still inside, but I was given two chickens over the weekend that are probably about to start laying. I'm concerned that one or both may have mites....eek!! SO, I've been reading up on mixing food grade DE in with sand or dust to help them clean themselves and kill the parasites. However, I cannot find what ratio of DE to sand to use...can some please in lighten me! Also, please give me other suggestions as to what I should do. I don't want to put the babies (they are about a month old) out in the coop to even introduce them to the grown girls until the mites are gone!! THANK YOU ALL!!!
