When to repeat ivermectin for mites/dosage for ducks?

[shiningeyes]

Sorry everyone, i know there are a ton of threads on mites/ivermectin but I just can't seem to locate exactly what I'm looking for. I was treating my chickens for possible mites and dosed them last wednesday with the ivomec pour on. Do I need to treat them again? If so when exactly? I've read everything from a week to two weeks to later. Also, I think I need to treat my ducks too. I was out this morning and picked up my hen and noticed a red mite on my hand. Though I don't know if it was an actual red mite, or one of the clover mites we have ALL OVER. But I figure I should treat them in case. Her feathers look a little ratty on the tips of her wings and tail. Thanks for any help!

You will need to treat your chicken coop for mites too. Permethrin spray works great. DE does not.
Usually people treat again in ten days.
I'm not sure about anything duck related though, sorry.
