Hi, All. So sweet Martha, one of our six silver Appleyard ducks, has always had a very distinctive way of drinking as seen in this video (Martha is on the right behind Mouse, our all-white silver Appleyard): We've always thought it was adorable, but we recently begun wondering if it was indicative of a problem. We searched some and didn't find anything definitive. Has anyone else seen this in their ducks? A few details: Martha is our smallest silver Appleyard but also usually the most feisty. She adores food and eats with gusto. She may be our drake's favorite girl. After her first drink, where she tosses her head back, she then drinks normally. The next time she come to the pail, however, 90% of the time she'll toss the first drink back again and then resume drinking normally. She'll be two years old this spring. Here's another short video: Thanks in advance!
