Ok, I may sound crazy but I have to ask. I have 2.5 week old chickens, 8 of them all hatched from eggs we got from a friend of ours. We have no clue as to their breed or sex. This moring I was watching the babies and noticed one of them opening his or her beak and stretching its neck like it was trying to crow but no sound was comming out. Is this just something all chickens do or do you think this is a baby roo trying to crow???
