Limping duckling

[mblack03]

Hi!

We recently took in three mallard ducklings that had been left without a mother. They're about 4/5 weeks old, and have shown no other issues or conditions until this morning.
When I came to check on them outside after feeding my big ducks, I noticed one of my babies, Moe, has developed a limp. Her left foot is fairly swollen and she's showing a huge reluctantly to walk.
Why is this happening, and how can i help her?

[The photo includes the swollen leg and Moe herself for reference. We have a little water pan for them to swim in and she's only wet, her feathers aren't matted or disheveled i promise :,)]

Have you looked into bumblefoot?

Did you take her to a vet, like I suggested in your previous thread?

Hi!! Yes

This post was from when I first noticed the limp; I've recently updated my most recent thread since then. Thank you!!
