That solid red doe, by far has the nicest conformation. I'd go for a kid out of her. The other adult goats all are built downhill with steep rumps and weak chines and toplines.
The kids look healthy. Their conformation isn't the greatest, but they're not terrible. They sure are cute! When judging kids, I go more by what the sire/dam look like, along with udders and pedigrees. They change so much as they grow.
