Well, first off WELCOME to TGS! I'm sure the folks here can give you very good advice! Another good website to start with is http://www.fiascofarm.com. I am a newbie too. This is my first year of kidding. So, I'll start till more experience comes on. Anyway, when I got my little ones I just filled the feeder and fed free choice hay. And of course fresh water. Goats appreciate warm water when its cold. I'm sure it depends upon whether or not they have any pasture? From what I've read, alfalfa pellets aren't good as a complete ration because they don't have the long fiber that hay provides...goats being ruminants. I feed my young goats just a handful of a 12% grain mix, just enough to make them easy to get a hold of. But, with full size dairy goats you might need more...someone will correct me here.
So, fyi, we require pictures. Tell us more about your little does! And yourself!
