So I am considering showing some of our dairy crosses at our local fair in September. It is non sanctioned...all dairy breeds shown together and last year there were two dairy goats I believe total. This means I would need to keep our does in milk. Normally they just raise their kids and dry off when done. Will machine milking them with a cow milker (we have a dairy farm) hurt their teat placement, size, or their udder? Is hand milking better if I decide to show them?
