We have 8 girls under 20 weeks old and just two more mature ones 4 days ago. The very next day the 25 week old gold-laced wyandotte laid our first egg and the next day too! yesterday no egg. I don't know if this is pertainent or not. The real question is that she is so vocal. Loud baaawwwkkk for seemingly no reason while all my other younger ones make practically no noise except when they get flustered. Is this something that changes as the chickens get older. Do they get a bigger stronger voice. It's not an egg song I'm hearing just long Baaawwwkks every minute or so Normal?
