We have two buffs and two australorps they are both about one week old. They are doing great! Active and fun. It has been in the 90s here so I have been taking them out to explore their coop in they day. They chirp chirp chirp in the grass. They also chirp whenever I walk by their brooder and just about all throughout the day. Is there anyway to tell a happy chirp versus a bad chirp?? Thanks guys!
