Is this behavior a sign of anything serious I should address/be concerned about? My 1 1/2 year old Orpington hen has become far less friendly (doesn't seem to know who I am any more) and has stopped laying too. She does not follow the other hens into the coop when I call them. Just stands out side looking confused and is afraid of me. Very strange...she used to come sit on our laps. Any info would be greatly appreciated. THANKS.
