@Leigti I am no expert on this but I'm pretty sure I've read that it could be from a B vitamin deficiency. The natural way would be to feed it some finely chopped high quality liver or some raw grass fed beef (this is what I did), orthere may be a vitamin drench at your local store. Someone else will hopefully chime in with their opinion, but in the mean time I would do the above right away, it certainly will do no harm.
OK, I can try that. She is only about a week old, but I guess it's no different than eating a little tiny worms. I will try it.
