Who teaches chickens what noises to make? Is it just nature? My roos have the same crow as some older roosters that live a ways away but I still hear sometimes when the wind carries the sound in. So far since the peeps have stopped I hear some crowing from the boys, but only other noises are kind of an odd cry from them. It's lower pitch than a screech, but they do it from time to time, and a few clucks here and there. If there are no other hens in the area, will my girls still learn the "egg song"? Do I have to bring my laptop out to show them youtube videos? I know some never do the egg song but for the ones that do, where do they learn it from?
