Please forgive me if this has already been a topic and has been answered. I've been getting an egg a day, nearly, that has been, well... deformed, kind of. I have ten hens and thay've all been laying since last October and their egg production is pretty consistent, I get between seven to ten eggs a day. Almost every day I get one egg with "warts" at the narrow end and the shell is rather thin. Sometimes, there's a portion of the shell so thin as to be almost missing and the membrane is visible. When I crack the egg, there are often tiny bubbles in the white. The deformed eggs don't smell bad and they don't float but I'm a little hesitant to eat them. They explode when hard-boiled so I just toss them. I can't figure which hen is laying the deformed ones. I'm only certain that it's not the EE because she lays green eggs and the deformed ones are brown, actually kind of tan-ish in color. Has anyone else experienced this and is it a sign of illness? Is there a treatment?
