I added to my flock about a month ago. Added 6 "spent hens" from an "organic" egg farm. These hens are just a year old, and since they've been on my farm, they lay an egg just about every day.... even with it being December (no extra lights in use). At first, they really didn't know how to act with their freedom. I let them free-range during the day. First few days, I'd often find them fighting amongst themselves, but now they all get along. One of the behaviors that I have noticed with these hens is something that I've never seen before in all of my other chickens. (I've had RRR, Bared Rocks, and Buff Orps). These "spent hens" are the Bovan Brown breed. The behavior can be described as a squat position they quickly assume when being approached. Wings spread, they crouch, and do a little too-and-fro step on their feet - in place. It's almost like a fear reaction. I've never seen this in any of my other birds! They all do it. They don't flee when I reach to pick them up, but take this almost "frozen in place" position. WEIRD!!!! Has anyone else observed this type of behavior?
