my hens are about10-12 years old, i think. they stopped laying a while ago, but now they randomly lay an egg. the albumin in the brown egg layers is cloudy, and i am afraid to eat the eggs. the albumin in the blue egg layers is still clear, but sometimes the eggs appear frozen (it's cold here! even with a heat lamp) - i can never find any info on eating eggs from old chickens (only about eating old eggs) - any advice??
