The things you are talking about all point to a shed coming on. During the last 2 sheds, my bp has dented one or both of her eye caps; its not because she's dehydrated, its just because theres a new eyecap forming underneath, and the old one is getting ready to come of. So don't worry about that. Also, as far as the wheezing goes, just increase the temps a little to be certain, but I think its just for the reasons that Robert Combs mentioned above.
