Jersey giant, about 3 years old. She's been not herself the past few days, though still eating and out pecking and scratching the ground. Couldn't put a finger on what she's doing differently, but definitely not herself. I just went out to the chicken area and saw her flopped over, presumably dead. Nope, a few minutes later, got up and walked a few more feet and flopped over again, appearing dead. When I touched her, she got back up, walked another step, and again, playing dead.
So she's clearly on her way out, but I don't know why. Looks healthy, and the rest of the flock is all healthy and fine and running circles around her.
I haven't dealt with much in the way of disease, but I was wondering if this sounds like she's sick, or if her time has just come? I'm mostly wondering what I should be looking out for, if I need to take preventative measures with the rest of the flock.
