I've noticed mites on my hens. Most just had a few but one girl was pretty infested. I'll be treating them with ivermectine and disinfecting the coop this weekend. My concern is that I have a goose and two muscovy that share the coop. I've not checked the webbies for mites, but I'm assuming they also have them. Can geese and ducks be treated like the hens with ivermectine? Treatment advice given by chicken rancher. IverMax cattle pour-on: 2 drops on skin at back of neck repeat in 10 days Good? Bad? Suggestions?
