I have an almost 2 year old La Mancha buck in with 3 ladies of about the same age. I have seen them come into estrus many times, and Brownie (buck) cover them, but still no kids. I give them free range on 3 acres with hay supplement, free choice on minerals and a mineral lick, and they do get a small amount of grain as I live in North Florida so we don't have the best nutrition in our pastures. Any advice? I know one of the does has had a kid before (singleton) and I have seen some bagging up on two of them does but no babies.
