We don't have hay as "fancy" as bermuda grass here!  LOL.  I have a grassy hay with some timothy.  No mold, no dust.  They've been eating the same basic type of hay all winter, too.  
It's been over 72 hours since he started showing symptoms and he has not shown any problems with his neck, no coughing, no bowel problems.  As I said, he is eating and drinking.  He is not crying or complaining.  He is sitting in that "henning" position, with his legs tucked up under him, like he does all the time.
Truly, I haven't really pushed him to get up, I'll have to check and see if my husband did.  I have extreme asthma and I am more the person who goes down and pets and watches and orders husband around.  
I did read all the symptoms of the various goat diseases and none of them were really that close...I sure hope it isn't listeriosis or polio...that sounds pretty awful.  
I'll have to find a vet in the AM.  Maybe my horse vet will stop by on her way out on calls.
