I went out to check on the chickens and one was laying down and kept blinking her eyes. I know that sometimes chickens do this but when I went in and everyone came running and she didn't I knew something was wrong. Especially when I reached right over and picker her up, no problems. Well her crop felt large and round and I went to massage it and clear fluid started to pour out of her mouth and I mean I barely put any pressure on her chest. I don't know what to do. Yesterday I found that I had forgotten to remove the cap to the waterer which would allow the water to pour out so they were without water. When I fixed it they all went to drinking like mad. Yes, I know my stupid fault. But I wonder if she could have overdrank to compensate and now... well I don't know. I just wondered if that could have something to do with it. I would think that I would need to get all of that out of there but I have heard that you can drown them if you aren't careful. I just need some expert advice on what to do. Please please help me out.
