Is this supposed to happen?

Question

I wanted a a baby Psyduck.
I had my Empoleon with Surf, Blizzard and two other attacks breed with a female Golduck.
When the Psyduck hatched it had two other moves surf and blizzard.
My questions are: How did it learn those moves, they aren't on Pysduck's egg moves list?,Can Pokemon learn two egg moves or more?

Answer 1

A Pokemon can learn 4 Egg moves at once. Also were the other two moves TMs/HMs that Psyduck can learn? If they are then that is the reason. TMs and HMs are passed down too.

They were the moves it learns as a baby Pokemon. Thanks SF!
