Knee buckling issue on Gander? (See video)

[geesechick]

My 9 week old gander has an odd knee buckle while standing that I noticed about a week ago. I've checked his legs and feet and all seems normal. It is pretty much constant, and doesn't seem to effect him in any sort of way regarding mobility. Just concerns me and want to make sure it is nothing.

Anyone out there have any thoughts? I'm think I am going to try and find an avian vet, but would love any feedback in the mean time...

Poor thing.

Lets see if someone can help out. I'm just not sure about leg issues in geese.

@geesechick did you supplement with niacin when your gander was tiny gosling? Any of us that use chick starter need to always supplement with niacin or nutritional/brewers yeast from hatch till at least 10 weeks old. That is when they are growing and need the B3 for leg health. I'd def seek out an avian vet if you can but in the meantime you might want to also start him on 150mgs of niacin in his drinking water 150mgs per gal of water or 1 tab of N/B yeast per cup of feed.
