Don't worry yet. She may move just fine. How long has she been broody? The one I had that flipped out had actually been sitting on her hidden nest for over a week. Unfortunately, she was not in a safe place at all, so I decided to move her. Last year I moved one three or four times. She absolutely would not stay where I put her. She wanted her chosen spot. That being said, I've moved several that are perfectly content to sit where I put them. More of those than the stubborn ones. I have a broody wanna be right now (she just weaned her last batch of chicks a couple of weeks ago) but I'm in MN, and this is not a good time of year. She'll keep them warm while they're little babies, but by the time they're old enough to be fully feathered, it will be early December. Just don't want to take that chance. We never know how cold it will be by then.
