Question: how big are foals when born?
Answer: Normal Birth Weights No matter the breed, foals weigh approximately 10 percent of their mother's weight at birth. That means the typical 1,000 pound thoroughbred mare gives birth to a 100 pound foal, the 1,500 pound warmblood mare's foal is about 150 pounds and the 2,000 pound draft mare's offspring weighs 200 pounds.
