Hi! I am fairly new to raising kid goats and am concerned about my 4-week old bottle baby. He will never drink more than a few ounces a day and half of the time I have to force it. Should I be forcing in even more? He will nibble on hay and grains. Also, could this be the cause of his laziness? He does not bounce around or play with his brother. He also gets cold very easily and loves to lay by the fireplace.
