My Henny laid one similar yesterday http://www.backyardchickens.com/forum/viewtopic.php?id=281249 - although without the blood. Nothing to worry about!Congrats!
One of my hens (Henny I think) laid her first egg today! This is my second hen to lay an egg as I am new to keeping chickens.I am just wondering if the egg is ok as it has some markings on it..... almost looks like it got stuck partly...
