Today after work around 1:30, I opened my coop because it was getting warm out. It was cooler in the coop than it was outside, and there was plenty of food and enough water to last a few more hours. When I opened the coop I noted one of my 1 year old hens laying on her right side dead. It was so sudden. She was laying yesterday and seemed healthy. I was short an egg today so I don't know if she died this moring or later in the day. Any help would be nice pease. These were my first chikens and my little children.
