Little scrapes I think from walking barefoot . Or should I say duckfoot. 😊 I would keep an eye on them because scrapes and things sometimes turn into Bumblefoot. You can put a little NONpain relief type antibiotic ointment on them or give them a spray of Vetrycin.
That’s what I have. Got two of them 10 years ago and one is still living the other died recently. Wonderful Ducks. And So So pretty. The part that’s blue is called the speculum.
Looks like she’s been biting at herself there maybe itchy
Use antibiotic ointment like Neosporin a couple times a day make sure it is NOTthe kind that has pain relief stuff added.
Cute duckling congratulations!
I have ducks ten years old who are still laying - not as much as my younger ones but still laying good eggs. I have one I suspect has a problem like your vet mentioned reproductive track infection possibly because I’m finding some soft and no shell eggs but still don’t know who’s doing them…...
