My wife and I are totally new to chickens. Two days ago we got a straight run of 12 australorps. We pick them up a few times a day to check for pasty butt and to get them used to being held, but we only hold each one for a few seconds. Is this enough interaction for them with us? They seem pretty scared of us every time we get close so we don't want to stress them out (but usually they don't want to leave our hands when we put them down!). Anyways, I don't know if they need to be entertained to avoid developmental disorders or something. Thanks for any advice!
