Looks like she is walking? I wish I knew what to tell you. I watched a video today of a duckling That hatched and wasn’t able to stay upright the person put it into a sock with head out I don’t know how long it stayed in the sock they didn’t say but it was able to walk after. Might be too late for your little goose but maybe she’d sleep in one? Just put her food and water close enough she can get it with out drowning.can she swim? Did you get the b complex?
