I just wanted to offer up a few words as my husband and I have drained similar on our dogs. First of all I would get a second person to help you. Animals move, and this duckling is tiny. It will help to have one person who is focused on holding the duckling still and in a good position while the other person works. Also I would use a headlamp so you can see well what you are doing, if you don't have one, maybe you can set up a lamp to be shining directly on the duckling. Consider a face mask or bandanna over your nose and mouth as well, trust me on this one. I like the idea of starting with a needle to see what you are in for before moving on to lancing. Also keep in mind the process may need to be repeated in a few days, this is often easier and sometimes you can just do a warm water compress to loosen/remove the scab that forms and allow it to drain some more. Good luck. You'll be surprised at what you can manage on your own. This clearly isn't healing on its own, so you really can't lose by trying to help at this point.
