This may be a stupid question, but I wasn't able to turn up any information when I searched for it. We got ten chickens to add to our flock of three older hens five months ago. Two are roosters and the other eight are hens. Every day now we get at least four tiny eggs, one regular sized eggs (I'm guessing our trust BSL) and one gigantic egg. How do I know which chicken laid which egg and which ones aren't even laying yet? Thanks!
