Awww Susan thats breaking my heart for you guys! I am by far an expert but I agree that something neurological is going on. Whats makes you so sure he was 100% fine before he left wherever you got him from? I only ask because if it wasn't from getting terribly bonked around during shipment, something had to have caused it. Have you thought about cutting his top notch feathers He is gorgeous but if I wear in this situation I would do it only to relieve the stress of not being able to see his new surroundings. Take some good photos of him prior to cutting, so others can see what he looks like fully feathered, so when it comes time to sell eggs or what not, they know what he looks like before-those who know you, trust you. I would buy Lav eggs from you from a bald roo! Ill do some searching around and see if I can find anything about this-in the mean time I honestly dont know of anything else to help..Im sorry..Nat~
