Hi and welcome to backyard chickens! I am sorry you lost the chick.

It is risky whey you introduce new ones to the flock. It works best if you put them in at night when you will be able to monitor them the next day.
My guess is brain damage. Silkies are prone to brain injuries because of their vaulted skull.
