I have gotten a few Ducks with bad feet. I did nothing except provide clean areas and now they have great feet with calloused spots. Lots of swimming with clean surfaces to walk on.
I didn't mean harsh to me..I meant harsh in terms of out come to the OPs Duck that is doing fine still..definitely picking away at feet that are okay could cause infection that the Bird doesn't need.
Wow..That's pretty harsh. I'd have dead Ducks everywhere if that was the case. All I'm saying is if the Bird is doing great then nothing needs to be done. Why cause issues to a foot that has healed itself...
Why fix what ain't broken?
If the Duck is fine, they also develop calloused feet and self heal if infection didn't get into the foot. So if yours is fine then zero reason for treatment.
