Weaning. The University of California, Davis Goat Facility weans its kids completely by the age of 3 months. Much depends on the individual; some kids are ready to eat completely on their own before that, but others need longer.
Latest estimates of average weaning age in the United States indicate that 70% of calves are weaned at 7 weeks of age or later. In addition, 25% of farms surveyed said they weaned calves at 9 weeks or later.
