There is a semi-wild Pekin that lives on a canal near me. Overnight, she seems unable to put any weight on one of her legs and won't even use that leg while swimming. We're trying to figure out if this is bumblefoot or some type of sprain. If she did have bumblefoot, would she still be using the leg when swimming? The leg hangs limply behind her when she swims. She has had some growths on the bottom of that foot for some time, which are shown in the attached photo. Thanks in advance for your help!
