I have 6 Buff O's and 5 RIR's, all hens. I did have a roo, but he was tearing the hide off one of my Buff O girls (he was relentless!) and I ended up culling him. I am planning on getting some SLW's in the next few weeks, just need to decide if I want a trio (1 roo, 2 pullets) or start over with chicks. I have been having a sort of feud with one RIR hen who had decided to be the head chicken after the rooster was gone. The wench would peck me and try to claw me when I went to pick up the eggs or just check the girls out before bedtime! We had a good old fashioned "throw down" the other night...I have various bruised peck marks and scratches on my hand and lower arm...she got her dignity bruised when I picked her up and gave her head a little shake and then put my hand on her back and made her squat! Last night I went in to check everyone and pick up eggs and she was suitably humble! No more coming up to me with her "What do YOU want?" attitude! Finally...she and I have been sparring for 'head hen' position for several weeks now...I guess I outlasted her! Anyway, love all my girls! I call them all my "Biddy girls" collectively. I do have different colored zip ties on some, but it is just too much hassle trying to remember names of hens that look identical!
