This hot mess, laid by one of my hens, is often referred to as a “lash egg,” and is a very misunderstood phenomenon in backyard chicken keeping. Lash eggs consist primarily of coagulated pus, not yolk or egg white. I took the liberty of renaming the lash egg more appropriately, a Pus Coagulegg. It’s got a nice ring to it, don’t you think? Unfortunately for the hen, the Pus Coagulegg is no laughing matter as the prognosis for a bird producing them is poor, at best.
