I'm looking into breeding a Stealth Rock Whirlwind Skarmory to use as a hazard switcher. I can breed Whirlwind from my Pidgot onto Aerodactyl, teach it Stealth Rock at the Move Tutor, and then breed both onto Skarmory.
My obligatory 1 direct attack slot has raised a question. I had originally been planing to use Steel Wing. But in looking at Skarmory's Egg Moves, I noticed Drill Peck. It has both higher accuracy and power than Steel Wing, at the cost of the chance to raise Defense. However, Drill Peck only comes from a very narrow selection of Pokemon. Neither Pidgot or Aerodactyl can learn it. Now on to the actual question.
If I pass Stealth Rock and Whirlwind onto Skarmory, can I then breed Drill Peck from a Fearow or Doduo/Dodrio and still keep Stealth Rock and Whirlwind to get all 3 moves on Skarmory?
