I have 20 hens. In the last few days I have found evidence that someone is eating the eggs. The other morning I opened the coop to feed. There were two eggs in the corner. (A favorite place for three of my girls) I turned my back to put food in the feeder. When I turned back one egg was missing. Three girls were standing there looking at the spot. Anyone have any idea how to tell which one is doing the eating? My egg production has dropped to 10 eggs a day. I usually get 15-18. I blocked the spot where they were laying and today I found egg yolk on eggs in the nesting boxes in two places. I thought of putting my game cameras in the coop, but I am not sure I would be able to tell which hen it is. Any suggestions would be appreciated. If I find the offending hen she will be in freezer boot camp for sure.
