I'm just doing a little bit of purrs and clucks every 15 minutes as I sit. I can hear the same all around me from other hens walking around, so I try and imitate them. Everyone is calling like crazy around me. This tom seems to be going down the mountain in the morning, and back to the roost at night. He won't reply to calls after the morning though.
I actually had a hen walk right up to me last night while purring and clucking. She was so close that when we met eyes, she threw dirt on me as she flew up and away.
