This is my second flock I've had.. I currently have 6 barred rock hens and 1 drake pekin about 26 weeks old. Ii raised them all from hatchlings, follow me around hop on my lap,shoulder, you name it. I have to that are my cuddliest that will hop on my lap or back (if I'm bending over), then they will "scratch and peck" like they do with fresh bedding or dirt. My guess is it's a happy response (happy chickens peck and scratch).. thoughts?
