The last two days I've noticed that my two year old buff has been laying on the ground of the coop .She isn't the most fond of being picked up, but she has been letting me and when I put her back down she takes a couple of steps and lays back down. I've checked for leg and body injuries, mites and egg bound. Not knowing why she is acting so odd I tried giving her half a baby aspirin and seeing if shells snap out of it. I rolled it around in my hand to get her attention but pecking at it to eat it she was about 1\4" to the side. I tried this three times and each time she's just a little off the mark. Any help would be greatly appreciated, she's my best layer and takes in any new chicks, broody or not.
