I wouldn't have the first clue. @Miss Lydia is who helped me with my jumbo. I only recently got ducks and she was my only one that's had an issue yet footwise
My jumbo never got that bad, as soon as her foot started to turn inwards, she started getting peas soaked/injected with the niacin medication until it stopped and she turned 16 weeks. Then it went to 1-2 times a month until she passed. I'd think about making a sling to put them in so they aren't...
