We just got six baby chicks yesterday from tractor supply. They chirp quietly for the most part but there is one that will randomly chirp extremely loud for a little while and then stop. Is he unhappy or maybe just a loud mouth? I read some other posts that said this can be because they are cold but we have a heat lamp at the top of their container, maybe 24" max from them, and they sometimes go in the box we were told to put in there to escape the heat so it doesn't seem like they're cold.. So I guess my question is could this one chick be an alert that something is wrong or just extra noisy? We're totally new to this so any help is appreciated, thanks!
