One of my runner ducks came up suddenly lame and when looking at her foot I found what looked like a very small fine thorn. I think it was a bee stinger as the bees are all over in the clover right now. I got it all scraped out and she had a drop of blood form. We put her in the pool so she could wash it out. Now she is standing around on one leg looking sad. She forgets to put the injured foot down before she walks and keeps falling over. We have her in the shade now napping with her buddies. Is there anything special I should do for her?
