Question
at what age will his testicles drop

Answer
A colt's testicles are often present at birth. When they aren't, they usually appear by the time the colt is ten days old. The testicles tend to ascend again after this, not descending again until the colt is somewhere bettween two and five months old - or older. After this, they may ascend and descend seemingly at random: on some days, you'll see two, on some days, you'll find just one, on some days, you'll find none at all.
