Duck is limping.

[Hhackleman]

My duck started limping a couple days ago. I brought her in and she has a bump on each foot that look like corns on a human. What’s weird is the side that is smaller, is the one seems to hurt the most. Anyone know what it is?

Its called bumblefoot and it is common in ducks, often caused because they walk on too many hard surfaces and not enough soft ones. Try soaking her feet in Epsom salt water, and providing her an area with a lot of soft bedding.

It appears she has Pododermatisis (bumblefoot). That can be characterized by inflammation, and infection of the plantar surface; there are several causes, but being housed on unforgiving bedding that promotes ulceration, and degradation of the squamous epithelium promoting bacterial invasion into the underlying tissue seems to be the most common culprit.

For a bird such as yours, you may consider soaking the leg in either an Epsom salt mixture, or an antiseptic mixture including chlorhexidine, or betadine. Soaking the foot will help loosen the eschar (scab) you're seeing to the point you may be able to gently peel it off with a pair of tweezers.

If excavation of the eschar is achieved, you can apply firm pressure to the area in an attempt to squeeze out any puss/ caseous material. After doing so, an antibacterial ointment or cream can be applied. To prevent subsequent infection, and damaging of the tissue, padding or gauze should be applied to the base and should be finished off with a layer of vet wrap. That should be changed daily, and if needed re-apply the ointment. Frequently antibiotics are indicated for "further along" cases such as your bird. You can obtain antibiotics online, in fish or bird form with an RX needed.
