Hello there and welcome to BYC!
Sometimes flock leaders know things that we can't see. So it is very possible it was because of the worms. Or maybe he just freaked out. Either way, keep him separate for now till you decide what you are going to do.
Great to have you aboard and welcome to our flock!
