Goose with underbite

[LulusLayers]

Yes I know the emoji is a swan. There's no goose!

, my 3ish month old embden goose seems to be developing a big underbite and a slight crossbill. I didn't notice any deformity at all when I got her, but it seems to be getting worse.

Anyone else experience this? Is there a cause? Anything that can help? She does eat and is definitely still growing but some food falls out also.

I uploaded a pic from when she was a baby, about a month ago, and then today for comparison.

I have no experience with geese, but with chickens, scissors beak and other beak deformities can worsen with age. Most people feed out of high sided bowls, and some wet a small portion of feed daily to help them to get enough. With chickens, some use dog nail clippers to slightly trim beaks to keep them aligned. That works for an overbite, but not with an underbite. And files also can be used. Placing a large stone that your poultry can use to hone their beaks on might be a good idea. I might make sure that your birds are on a balanced diet with good mineral/vitamins. Here are a couple of articles that might be helpful:
