Is the udder supposed to be hard...? Because I have a nubian who has this huge-o-mungo udder, and there's like milk pouring out of it. But when her kids try to nurse, she lifts her leg up and softly kicks their head... and now she's not really even letting them nurse... what does that mean? It's not mastitis, is it? And the kids only seem to milk on one side, where the teat is softer I think. Also, do all mothers make noise to their kids? Because I have one goat that is always calling her kids and one that hasn't even made a single noise to them since they were born.
