I have a five day old Rouen/Pekin mix, hatched from some eggs my dad gave me--so this is my first time with ducks. This one had been wetter than the others. I noticed today she's smaller, with her head twisted to one side. She's got discharge from nose, mouth and eye. She was rolled over when I found her and doesn't seem to have much energy, though she flails sometimes. Is there any thing I can do for her? She's with one other sibling who is very healthy, and two more went to a new home yesterday. If this is New Duck disease, should I separate them? I can send the third with the other two, or would that cause the bacteria to spread?
