I have three hens (2 barred rock and one americauna) which I raised from chicks this spring. This winter they have been laying very well. In fact, on average I get 2-3 eggs per day and at one point I was getting 5-6 eggs per day from these three chickens at the beginning of this winter. They seem very healthy and happy, are fed organic feed (with the occasional scratch) and they have lots of room in the yard to move around. This egg (see photo) was layed by one of them last week, I don't know what the others in the frig are like. What is going on? I've seen a speck of blood in chicken eggs before but not a bloody egg. Help!
