We've had our three, 3month old hens (barred rock, orphington, ameracana) for a month now and are starting to get to know them better. I've noticed that they seem to make three categories or classes of sounds. One sounds like chirping and they seem to make this mostly when they are settling in for the night on their roost or when they are waking up in the morning. The second category is like "bawk" and they seem to use this to yell at each other or at me if I approach without treats. Occassionally they make the third type of sound, which is like a small dogs growl. This growl lasts a long time and they mostly stand very still when they make it. Any ideas as to what these sounds mean? My dogs have different sounds they make and I have a pretty good idea what each sound means so I am trying to figure out if there is a similar "translation" with chicken. Thanks!
