I never stop learning with poultry! I have Ameraucanas that are 7 months old and have been laying for a couple weeks. I came home today to find an egg in the nesting box with a soft shell. Not the first time I've seen this with young hens... but I also noticed a mass of clotted blood in with the yolk and albumin. Not just a spec but a loonie sized mass of blood (that's the funny Canadian money). I haven't noticed any signs of poor health with my flock. Has anyone seen this before? I'm worried about my fuzz faces!
From what I've read, if it's just one egg, it's nothing to worry about. Seems to be more likely for new layers or when pecking orders are changed. Could be a well-timed ruptured blood vessel while the egg was forming due to fighting or getting startled. If none of the hens are acting weird otherwise or bloody around their vent, I wouldn't worry about it.
