I have this idea about chickens who "work" for a living laying eggs, catching bugs, semi-weeding the yard, amusing me with regular chicken behavior; I think that's enough for them to do. If I had a house chicken, I might spend some time teaching it to do "tricks." But mine are already pretty clever. Clever enough for me to enjoy their own, innate antics without adding to their repertoire.
However, I DO like it that they will come running, even when free ranging, if I call out, "Chickens! I have CHICKENS!" which is what I did every time I opened the back door to go out and do chicken chores, or just to spend time with them.
Yes, I was thrilled to be a first-time chicken keeper. And that hasn't changed.
I don't think it's a "trick" when Bernadette jumps into my lap when I'm sitting in a chair in their run, or in the yard when they're free ranging. She just wants to share chicken stories about her day. Or when Matilda circles me, chumbling away and pulling at my pants legs. She just wants attention. Or when Betsy does a little jump in front of me, about 2, 3 inches high; she wants me to pick her up and carry her around. Or when any of them squat so I can skritch the back of their necks. That's normal behavior for chickens who "like" the human a whole lot and are submitting the way they would to a rooster.
It's all quite clever. I love 'em for it.
