My favorite hen is about 2 1/2 years old, hasn't laid an egg for over 9 months, she's a RIR. I've noticed she's seemed a little thinner than usual, she's eats some and has been drinking water, not sure about today, but today I've noticed she's very lethargic, not moving around much like the rest of the flock what poop she does do seems normal, a few times last year she had only water coming out instead of "normal" poop and seemed fine then, moving around and wanting to eat. But the weird thing is she pulls her head into her neck and closes her eyes like she's sleeping while standing. My chickens are in a closed run ( too many wild animals out here) and they have plenty of food & water. She goes in the coop at night but she's just standing around with her eyes closed and not moving like the rest of the hens, just really seems out of it. One other question.....I have 5 hens all 2 1/2 years old and only one is laying eggs about 2-3 a week. I have 2 New Hampshire's and 3 RIR. I'm lucky to get 15-20 eggs a month now, any idea on them not laying too?
