My two year old Cinnamon Queen has always has always laid thin, striated shelled eggs--sometimes from the roost (outside the nesting box). This morning she did not lay at the usual time. This evening (outside the coop), when eating treat of mash and scrambled egg, she exuded a partial soft-shelled egg with poop on it. Her behind looks generally messy. She is not a bird that likes to be touched.
Can you post photos of the eggs?From looking at other threads it seems that "fly strike" or some type of worm are possibilities.
You're looking at other threads and it seems like FlyStrike is a possibility? You see worms/maggots on or around her vent?
Photos?
IF she has FlyStrike, then that needs to be addressed asap. Maggots will damage tissue and often if not caught and treated early, a hen can die.
