i thought id post this here rather than in the emergencies section as more people here have ducks than over there i think i noticed 2 of my ducks limping yesterday and finally caught them today (scovies) for a good look they both 'bubbles' underneath their feet, both on the webbed part and the toes. they are soft and squish...i think fluid filled? my first thought was bumblefoot but have only ever dealt with that in chickens, and that wasnt blister like they were more solid lumps? any ideas what they could be and how i could treat it? could it be blisters caused by the cold? its been frozen over for weeks here and snow covered so they've been constantly on ice so to speak.
