The first litter of our own is 21 days old today! I realized I've heard some different reports on when they should be weaned. I'm aware they *could* be weaned today, but wondering if they would be better off closer to 4 weeks? What works for everybody else?

They are eating, and drinking, but still nursing a lot as well. Their weights are good, and with 7 of them they're fairly big for no older than they are, don't know if that plays in either.
