I just received my silkie via postoffice and they said he was crowing up a storm but when I picked him up he never made a sound. He after 3 days still doesn't make a sound. And he just kind of sits there. He wont eat or drink or crow. He kind of makes a growling sound. This is my first grown roo. Do silkies act like this or is he possibly in shock or do you think the po might have hurt him? What do I do?
