I ordered the variety ducks Ideal had in December. I put my ducks outside today is supposed to be 40 on up so I don't think its to cold. I am not even sure what kind of ducks I have but 4 of the ducks are just black and all of the black ducks within a hour almost died, I took them in side and they seem to be doing a little better but when I rinsed them off I noticed they had bald patches on them. Any ideas?
