I have a lady amherest male that should be 5 this year if he was 2 like I was told when I bought him. The last week or so he seems to turn his head from side to side almost non stop it is almost like his vision is going in one eye and he keeps turning to see what going on, he seems healthy and does not have any problem getting around, but I can walk up to him and almost touch him before he takes off which is not normal for him.
