I have 6 hens and NO rooster and my eggs are lovely...sometimes just a tiny speck of blood...from straining I think. However, as it is winter and my girls are not laying well, so I sometimes get eggs from a neighbor to sell to my co workers. The neighbor DOES have e rooster. Today for the second time I was told by one of my 'customers' that he cracked an egg and it had too much blood in it for him to eat.... the entire yolk was surrounded by a ring of blood. Last week I was told almost the entire egg was blood filled. What is going on ??
