I went out this morning to find my 4 month old Silkie laying in his cage. He could not stand up and his legs were out front of him like he was sitting on his butt. I brought him inside and washed him off because he had pooped all over himself. He is eatting out of my hand and seems to have control of his neck. I then saw a large bubble "blister" on the back of his neck under the skin. What should I do? I gave him some Vitamin E and wrapped him in a towel to keep him from rolling around while trying to move and flap his wings, UPDATE: I found another Silkie today with a weird problem. He was pecking at the air. He was trying to eat and kept pecking trying to get his food but he was about an inch too short of reaching it. I checked his eyes and they both look clear. He is walking fine.
