Do Egg Moves work in Egglocke?

Question in title. Played for the first time in a while, decided to do an egglocke and use Espurr because I love that blank-eyed little cat. I tried to give it yawn, barrier, scratch, and trick, but only scratch loaded. Did I do something wrong?

Bump and an update I guess. Just tried loading a Phanpy instead, and the egg moves worked for it. Is this glitch limited to the Espurr line?
