Any advice please! My 17 week hen hasn't laid any eggs yet. This morning during chores I found her against the wall acting sick. She had watery chalky poop and moves very very slow. Is she really sick or do they act like this when close to laying the first egg? I'm concerned. I know it's not much info, but I don't hav anymore. And I'm scared to lose her or possibly the rest of my hens. I hav separated her from the rest of the flock.
