One of my hens stopped laying for over 3 now, she is over 4 years old and a little on the fat side plus she has been a little stressed, (i know that those can be factors that causes no eggs), and if that was the only thing i wouldn't be to concerned because i can help her with that. What i'm concerned with is she doesn't leave her nest ( out of 3 weeks she has only left the nest 2 time, first time she went out of the coop and the second time was to switch nests), she doesn't poop very often but when she does it's a lot, she doesn't eat or drink unless i bring it to her. i can't bring her to the vet because we are to far away. Please if any one has had this problem any advice is needed.
