So I have 6 - 3 week old chicks and every now and then one will chirp just once pretty loudly and repeat every 20 seconds or so. It's like she's calling me or something because it seems like if I peek in on them they all look up at me, I walk away and that's that. I'm very interested in learning all about their behaviors and there doesn't seem to be a place on the learning forum for that. Can anyone direct me to the right place to learn about chicken behavior? Thanks so much!
