I like a little extra condition on a goat, personally.. I was just talking to a buddy of mine the other day and mentioned one of our dairy does who's like a BCS 2 or 2.5 right now...she's super skinny. She gave birth to 23lbs of baby about 10 weeks ago, and is raising them naturally...at 8wks, the trio weighed a combined 106lbs. And she turns her nose up at grain.
We know that's why she's skinny, so it's not like it's a mystery or anything...I just don't like it at all.
So anyway, I mentioned to my buddy (a very experienced herdsman) that it worried me a lot for one to have ZERO reserve on it in case something bad happens.. His response was "Yep. If they're already skin and bone when they get sick, they've got nowhere to go but
dead."
So...keep a little fat across those ribs.
Not OBESE, of course...but a nice SQ layer of fat across the ribs comes in handy if the going gets tough.
From the picture, I think your goats look great.
