Well Vegas not only pulled through but ended up a spoiled lil pet . She has since been weaned and sold to friend who is a vet tech as a yard pet. I was going to keep her.. But really I need to stop trying to keep everything born on my property and stay with in my budgets. When she was a month old i got a day old bottle baby from the dairy to keep her company and to teach her she was a goat and not ppl. At a month old she was the same size as the day old baby. And when I sold her she went with her new companion . She lives about 2 miles from me across town and I get to see her on the time.
