I have a pure LaMancha doeling, born in March, which does not seem to have "growth" to her. She's healthly, happy and alert, just very fine and doesn't seem to be growing a bit. I'm guessing her around 50 lbs. Is there any suppliment I can give or is she just going to be a runt? Love her anyways, but I'd love to have a kid or two out of her someday. IDK if she will ever grow enough though.
