I'm just wondering. We have two red sex-links that have been laying for about a month and we have a 3 month OP hen and a OP roo. I've never heard this egg laying song I keep reading about. I've been out there while they are laying but never before when they go into the box. I've also been out there when they are done and have never heard it. Could it be that I'm just missing it? Their really pretty quiet birds all day too so maybe they're just not as verbal?
