Janet was walking a little funny at lunch today. Then tonight when hubby when to put them in the pen, she couldn't walk at all. Looks like 1 leg is more of a problem than the other, but when she was out of her pool, she couldn't walk. Nothing looks broken and I can't find any wounds. She was perfectly fine first thing this morning. We have her in separate pen with heat in the garage for tonight, but I am clueless. Could this be a niacin issue? Do ducks have strokes? Could too intensive mating make her temporarily lame? Tomorrow morning I will get vitamins for her water and some brewers yeast just in case.
