When i went to check on my pekin ducklings i found them all huddled up. When i went to pick them up i noticed one had something wrong with its leg. It can no longer walk. The leg comes inward, instead of the usual spraddle leg (i think thats what its called) that comes outward. They are about 1 and a half weeks old. What should i do? Since its not a day old duckling his/her leg is thick, so its not as simple as a band-aid or something.
