I'm about to dip my girls. My hubby is anti-chemical anything on our chickens, so that leaves me with few effective options. Thankfully he didn't get on my case about it when I had to treat our flock for fowl pox, but I convinced him the antibiotics were absolutely necessary for their survival because of secondary infections. Only one shows signs of scaly leg mites, but I figure it's probably best to treat everyone at the same time, as I have young chicks in the run.
I got the idea from a former post on here to use neem oil and make a dip out of it (2tbsp. to 1 gal. water). Neem oil is supposed to be effective against many types of insects and parasites, but it's more expensive than the mite/lice sprays. People use it to spray their gardens, so I'm not too worried about it's safety.
We'll give it a try and see how it goes, I guess. But if it doesn't work, I'll have to sneak in a Permethrin treatment while DH is at work to avoid the argument. I try my best to keep things natural, but sometimes effectiveness matters more.
