I've had this buff Orpington (I believe it was a 5-6 month rooster). Well I walk outside to see that my duck (the guardian) starts going crazy. Usually he does this if something is wrong. I see my roo in the corner having what seemed to be a seizure. I didn't feed it anything bad. I clean the run 3 times a day so I don't see what might be the problem. Unless he was born with some disease or disorder.
