chicken freaking out?

[CochinBeauties]

My 7 month old miniature dark cornish hen is suddenly very freaked out. I dont know whats wrong with her. She keeps having spaz attacks and jumping and ducks like something is trying to attack her no matter what. She is twitching quite often as well. She just woke up this morning very scared and I want to help her.
She sleeps inside at night because she is too small to be outside in the winter. Im keeping her inside today because this is very worrisome to me.
Whats going on?

Thanks

When you say inside, do you mean in the coop or your house?
Something may have tried to attack her in the night. Is she being picked on?
I have heard that if they get a spinal injury, they will twitch. That is not likely it, but something to think about.
