I personally don't think that is a bad deal, like I said I'm offering a jack and jenny and asking $2,000 half of what she is. There is a suprising market for little donkeys but if she is not having luck finding a buyer, isn't prepared to keep them she should knock that down to pet-only price.
I don't really know though without seeing the little guys.... Yup, I'm prying for pics!
But really if they have good confo, good personality, and are small (under 36-much smaller for a jack) they can get quite pricey. Especailly if they have some color to them.
