The eggs we get are VERY different tasting them the stores too. Hubby and I cooked each others eggs so we didn't know which was which when we first got them and MAN we could instantly tell which was the store egg! This was way back before we got chickens and they were all free ranged hens too. Never had eggs fro hens that were not free range so don't know if that is it or not. All I can say is they are WAY different...dark orange yolks! Just YUM. I would let them free range!
