Recently, my 3 ducks got out of their yard and are in the near by lake. I can see them but i have no way of getting them. I did get one though. She stood in a neighbors yard for about an hour quaking. She also looked she had a bump on her neck.i felt it and their was a bump. Is that bad!?. Also, could it be a disease ? I just want know that to see if i should quarantine her from my other ducks. Also, will the ducks in the pond that i couldn't get be OK? Thank you, i am very concerned. They do seem to be very happy on the pond, though. They still come back for feed outside of my fence, but they will run away every time i try to make a move.
