The 5 NN hens I have are only above the Barred Hollands in my flock. They will get a pen with the new young Dorkings when the Dorkings are a little bigger. That will be 7 hens for the Red Dorking cockerel. The older hens ought to keep him in line. Of the new chicks, the RI Reds seem to be at the bottom of the pecking order. These are the old style Dark Red RI Reds, not the hatchery type and they are very friendly but slower growers than all the rest. Here is one on top of their water the other day.
