One of my WH ducklings started limping today, and is very quiet, and tired. He doesn't get up if he doesn't have to, and once he does it's like his left leg is stiff almost. I gave him some vitamins in his water, and he has food. He wouldn't touch it at all at first, but has since ate a little, and drank some. Any suggestions for this little guy? I'm worried about him, and just looking for any ideas that may help him out.
