I went out with my hens this morning and they were acting so weird! For the past few days when I go to pet them, they crouch down with wings out a little. I'm pretty sure this is mating behavior. BUT, today, they wanted to be on me! They would jump up on my shoulder, or my arm. One of them seemed to want to be held, and liked having her head tucked under my arm. I'm suspicious because so far I have some strange things happening to my chickens! So this is normal behavior, or are they being weird?
