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.
Make small amounts of calf starter feed and quality grass hay available to the calf starting a few days after birth. Measure how much dry feed your calf is consuming. When your calf is eating at least 1 1/2 pounds of calf starter per day, you can start the weaning process. This typically happens at 6 to 8 weeks of age. Reduce the amount of milk replacer in the calf's bottle over the course of a week until he is drinking almost entirely water from the bottle.
