Yay! So you did hold her upside down for a minute to get her calmed down? Glad it worked!
Yep! She squawked and flapped until she was completely inverted, then she calmed right down. I turned her upside down very slowly and I held onto her body the whole time - didn't have the heart to hang her from her legs like they showed in the "Chicken Whisperer" section of the book I'm reading. She didn't squawk or flap at all after that, not even when I set her in the chicken tractor. She and the other girls have been in the tractor since that moment, and I've been watching them. She hasn't caused any of her typical ruckus that she causes with the other birds, either.
