I have six young chicks that are only 5 weeks old. One or more of them is making noise that sounds like a roo only between 6 and 6:30am. When I went out to see who is making all the ruckus so early in the morning, they all hung out at the feeder, cheeping and eating. Could my neighbor be tricking me to get up in the morning? It is kind of funny seeing a sleepy woman run out to the chicken coop in her nightgown when its 38 degrees. We opened the fence into his yard so he can enjoy the chickens too, so our relationship has always been good. He could be having fun with me. What is the youngest age you have heard a roo crow?
