My sister found this in the coop this morning. So far all five of our girls have been acting normal, eating, pooping, etc. We've been getting at least four eggs from our five girls but we're only getting one blue/green egg a day from our 2 EEs. One had laid eggs all winter just like the other one did the winter before last (no extra lighting used). Our Welsummer doesn't lay as often as the other hens but after four days, she laid 2 days in a row (she usually goes about every 2 days). The other two are every day like clockwork after winter. So how do I know who this belongs to and what do we do now? There was no shell. Thanks!
