So the "chicken lady" at my local farm supply said that you can sex chickens fairly well by flipping them on their backs and watching thier legs. Roos, she said, will pull their legs tight against thier bodies. Hens might pull them up when you flip them, but eventually they will relax the legs and let them straighten out and down -- away from the body. Anybody heard this before? We have a polish roo and he holds his legs tight -- all the hens drop theirs, eventually. (I searched sexing chicks and didn't see this method mentioned). The other question has to do with the almost instantaneous paralysis or sleep that overcomes most chicks when you flip them on their back (in your hand). They seem so relaxed. Are they, or does it cut off the blood supply to their head or something?!
