Just when I think I have a handle on this chicken-thing...
I went into the coop last night to lock up and saw a girl in the nesting box. I thought it was weird, but assumed she was just trying something new. This morning she was still there, then this afternoon she was there again. She had managed to flatten herself into a pancake shape, too. I started worrying that something was wrong, so I pulled her out and put her on the coop floor and, flop, she assumed the pancake position again. I flipped out, thinking she had some dread disease, that her legs were paralyzed, wondering how to isolate her, when she noticed I had brought blackberries. She hopped right up and trotted over to the bowl for a treat. I breathed a sigh of relief and headed back to the house.
As I was walking back it struck me. She was on an egg! Is it possible she was trying to go broody? I feel like an idiot that the possibility didn't occur to me immediately. (I need a forehead-smacking smiley here) I was extremely close to sticking her in a kennel and forcing vitamins on her.
If she is broody, it figures. I finished hatching last week. There isn't a fertile egg on the place...
