Dag! I am such an idiot. I decided to check on her and picked her up off the nest to check her for infestation. Stupid! We had taken her off the nest to move her to the broody box and she had been fine.
Put her back down and she stepped on and broke an egg!! Clearly, fertile...
We have our first broody!! would have been happier if she had done this in the spring, but Oh, well.
We were going to leave her in the coop, but the other hens were laying on her - I don't just mean laying their eggs under her I mean laying on top of her! Then they started pulling her...
