chicken anxiety.
by touching/pecking others she can turn their mind into that of a frightened chicken. scared out of their minds they run and jump around trying to flap their "wings" and just pok-pok, scream and cry. they're stuck in this state for 12hours unless they'reable to calm down enough (very difficult) to try regain their consiousness.
if she uses her quirk too much or she gets too stressed, she'll start to act more like a actual chicken -> she poks and get's startled very easy.
