I just got two mallard ducklings today after one of our campbells died. we originally had just two and didn't want the alive one to be lonely ( shes about a month old). The mallards have very red skin and ones feathers are kinda ruffled up a bit. The place where we got them said their fine and they all looked like that but when we got our campbells (from a different place) the people also said giving them medicated feed was fine and thats how our Campbell died so im not so sure I trust them. I want to see if there is anything wrong with them and if there's anything I can do to help them. I put a picture you can see the worse one I cant get a good angle of the other but hes mostly the same.
