I have a six year old Buff Orpington hen that is starting to grow spurs!! She didn't lay an egg at all last year, and only a handful the year before. (it's been nearly two years since she laid an egg) During her first two or three years she was an excellent egg layer. Could she have a hormone imbalance? I know hens sometimes have spurs-- it just seems odd for her to be getting them at her age!!
