Hi All, I've been reading up on the scaly leg mites and have determined that that is definitely what my hen has. Today, I completely cleaned out the coop and put new shavings in and liberally sprinkled in DE. My question is, I only have one hen that has any symptoms...so do I have to treat all of them? Oh, and are ducks susceptible to them too? I've got ducks that will spend time in the coop until we come out and herd them into their own house. Thanks for any advice.
