I'm a new egg...got my coop up thanks to help on here, got 9 of my 10 pullets to about egg laying time.... I'm getting an egg here, 4 there, etc. All 9 of my hens are in the same coop/run, how do I determine which hens are laying? Should I start to separate them somehow and monitor them? I need to get down to 4-5 hens for the winter based on square footage of my coop, I wasn't planning on so many of my chicks making it to maturity....and I only want to keep the best layers. Thanks!!!!
