I have 2 does that are about 18 months old and delivered one kid each in January 2014. I don't know anything about their lineage other than they were bought from a dairy in Oklahoma. These 2 does are producing about 1 quart each per day. All my other girls are producing 1/2 gallon to 1+ gallons per day. A professor at my daughter's university said that if the doe only has one kid on 1st breeding he sells them.... I respect the opinions that I've read on this forum, they've been sensible and down to earth. So, should I keep milking these 2 does & breed them again in the fall before deciding to sell them...OR...is this as good as it gets for these 2 ?? Since I don't know their genetics how can I tell?
