I have a 12 week old gold-laced wyandotte, who is usually very fast moving in everything she does, she flaps around wildly when I feed everyone and usually gets very excitable. Yesterday, I thought my chickens were being very lazy in general (all of them) today, I notice most of them are back to normal, but my gold laced wyandotte is still sitting around not moving around much. I picked her up and she didn't resist me at all, and usually she flaps around and tries to run away. Shes been sitting there not moving much, didn't eat when I called fed them this morning and wouldn't even drink water until I brought it next to her. It's almost like she is moving in slow motion. She's been vaccinated for merek's and shows no other outward signs of illness. The only thing I can think is that shes getting too old for the starter chicken crumbles I have been feeding them, but would that really affect her like that?
