How much would be a fair price for her? Does her eyes make a difference in sales price if there's a demand for it?

I don't breed ish, so I'm not sure what that market looks like, but I do know that her eyes won't really add anything onto any prices you set her for. Outside of being pretty there's no difference eye color makes.

The pricing will depend largely on her week 4 and then how she trains further. But she will probably fall within the 400k-600k range, again depending on training
