I was under the impression that they did not, however this is only the second time I've really owned a duck, and the first time I was young. Upon closer inspection while sitting with a duckling in my lap, I noticed a rather large claw on each wing. Surprised, I tried to get a glimpse of the wings of the other ducklings- I will definitely check when I decide to chase them down to bring them in for the evening (I am babysitting them as they sleep in the yard after playtime)- but I couldn't tell if they did too or not. Even if they do, they are all from the same pen/possibly same parents, so that may not tell me much. So.... do they? Are they supposed to? I also have not taken a close look at the other ducklings I have (the one with all the attention is my indoor special needs duckling, who doesn't mind being held) but I believe they all have brown eyes... while this one has blue eyes. They all have bright orange beaks and feet.... this one has pale pink beak and feet. Since I'm terribly inexperienced with ducks, I am once again left wondering why this duckling is different. Out of pekins, runners, muscovies, and rouens, do any of them share these qualities, blue eyes and pink feet/beak?
