She's older and her wing feathers are already coming in, so she may need to be wrapped for five days or more. :/ It's pretty simple though, my best advice is to use PAPER TAPE, you know, that blue stuff you find at the craft store? It's not terribly sturdy but it comes off easily in water, and that's what we want. The last thing a ducky needs is to have sticky stuff caught right on her blood feathers! Just fold the wing up and wrap a few layers of the tape around it, just like you would an elbow or wrist. Make sure it's snug, and then try to keep her out of the water for a few days. Easier said than done. You'll have to re-wrap it several times during the process, but as I said, it's better to have tape that comes off too easily than tape that sticks and pulls on those sensitive blood feathers! Here's a photo of a well-wrapped wing for reference: Now if she keeps picking at it, you might have to put her in "the sock of shame" like I did for Wobbles. I used an actual sock because he's teeny, but the standard is a nylon since it's stretchier and more comfy for the bird. Here it is in all its hilarious glory: Buried somewhere on my camera is a photo of Wobbles in his little navy green sock, he looks just like a tamago nigiri sushi! I'll have to find it for you.
