Hay all. I am just doing some research and have a few questions. I have had 2 ducks before ( In with my chickens ) and they where great, no disease, lice etc. I only had them for a short though. 1) I am just wondering, what common diseases do ducks bring? 2) Do they get lice, mites and worms? 3) What is the worst disease a duck can get and how bad is it? 4) Would having mostly ducks, but a few chickens with them be ok? The chickens would be housed separately but will free range with the ducks. 5) Finally, for those who have ducks and chickens or have had both. Which animal is more disease, and especially mite and lice resistant. Any help is much appreciated.
