I recently had a roo shipped by the postoffice. When I received him they said he way crowing and carrying on. He has not made a sound since I got him home. He won't eat or drink. He also does not respond if I put my hand infront of his eyes. He also ONLY walks backwords. Did they injure him? He responds when I grab him. Thats about it tho. Is this head trama? What do I do? What can I do?
