Hi, I'm looking for a little advice with a hen I've got.

She's a white bantam Silkie and seems to be having some trouble walking and staying upright in general. Whenever she does stand up she's very shaky and can only take a few steps forward without sitting down again or crashing down. Near as I can tell there's nothing wrong with her legs and feet, at least visible and her feet are gripping properly.

Any help anyone can give would be much appreciated as she's a lovely little thing and I'd hate to have her put down.
