I have 6 chickens who are a little over 3 months old now. They are in their coop full time and I introduced them to their run a few days ago. I have 3 Black Sex Links and 3 Rhode Island Reds in my flock, my BSL's seem to go in without an issue, but my RHR's seem to be a bit on the "not so smart side". Any suggestions?? I am also wondering a couple of other things like when should I give them scratch and why am I finding feathers everywhere? They don't have bald spots or anything, but I even witnessed one being somewhat snippy to my other one and pulling a feather out. Should I have cause for concern?
