We lost a hen yesterday, she had been acting a bit funny since we returned from a vacation about one week ago. Yesterday, she wouldn't move,eat or anything once she was out of the coop. (We free range/ pasture raise). Today, everyone seemed happy and healthy. My daughter noticed another hen near the water spigot that now seems to be close to gone. These hens were "inherited " two years ago with most of my flock. They are about 7 or 8. No one was showing outward sickness signs. They all occasionally have dirty bums, but I had noticed a lot more soft-shelled eggs this spring. We have (had) about 20 hens, so trying to figure who was laying them is pretty much out of the question. The two that I mentioned are gold stars/ cinnamon queens not completely sure. I have the rest of the flock, about 6/7/8 year olds, and six that are almost 1. They all seem to be thriving. Any ideas?
