One is definitely lunging to peck at me. She used to be my sweet baby and loved to cuddle. When I bring treats out to them every day like spinach and kale, she's always comes running and she takes the food out of my hand when offered. But lately when I don't have food, she postures and lunges at me. At first I thought she was thinking I had food in my hand but it's a different sort of behavior. The other one is more skiddish. We've raised them from chicks so I assumed they'd always be fairly tame with us. They are now 14 weeks. old. Do they have a teenage rebel stage? I don't know if this all started when we upset the balance by removing the cockerel we thought was a girl.
I do have a 6ft privacy fence.
I like the idea of separating the older girls for a bit to allow the young one to explore and adjust to the coop and run.
I also wanted to add that I had one chick that went kinda mean in the 2-4 month old range. She would just run up and start pecking me, hard. I kept her only because she was the first chick I ever hatched and because she was the ONLY female from that hatch. I swore I would get rid of her sooner or later. She mellowed out when she started laying. Now, she's 7 months old and the very nicest of all my chickens. My only problem with her now is that she wants to walk between my feet while I'm in the yard. It's hard not to trip over her!
