I have 23 free-range hens. I'd like to know, for flock management and breeding purposes, which hen lays which egg and how many they're laying each week. I'm out of ideas on how to accomplish this. I've thought of a video camera, but I'd have to watch hours upon hours of video for several days. I've also thought about putting a hen or two into a crate in the coop for a couple of days to see what I get, but I'm afraid that I'll stress them out so much that they'll be off their normal behavior. Has anyone else with larger numbers of free-range hens figured this out? It's only going to get worse when we double our numbers this spring. Thanks so much.
