What Alice said. I would milk her. But then I use a gallon of milk every five days. You can feed the milk to your children, your dogs, chickens, hogs, or give it away to someone who's baby can't drink baby formula. I had a neighbor in Arizona who raised three children on goat's milk that I gave them.Milk out the colostrum. Package in two ounce containers. Freeze it.
If you don’t want to use milk after that, let her dry up naturally.
