I am not sure how old they are. I am guessing 5-6 months... Who knows.....
Egg song? Lol...errrrmm... I guess you mean clucking while laying......... Idk.....Guess everyone is different.
Hope they start soon for you....My chickens look just like these and we havent seen any eggs yet...plus we just got them Saturday.....so I dont even know how old they would even be.........
