Oh, and an update: Both ducks have significantly reduced swelling on their feet. Paprika seems nearly 100% back to normal size/shape with exception to the small patch of skin that sloughed off of the top of one toe. I am going to continue to put ointment on that and keep it very clean. Raspberry's feet are still puffy, but MUCH better. I'd say about 75% recovered. The skin looks papery and it may fall off, but I think she's recovering well. This is an awful thing to go through...I hope no one has to face causing an injury to their animals like this. These poor little creatures count on me for their safety and health! They are so sweet nonetheless. My daughter Hannah is hand feeding and watering them. I wish I would have taken a photo of the blisters when I first noticed them. It might have been helpful to someone. Oh well, I'll try to photograph them tonight.
