just a thought on the crate/pen screaming. He's terrified. He's alone and in a strange place. When I brought Seger home, I put him in a crate and put it right on the bed with me so I could sleep with my hand in the crate. Others have slept on the floor by the crate or IN the pen with them. He needs your nearness right now. Try that at night and see if it doesn't calm him down a bit.
