Where are our eggs??

We have been expecting Brave Chicken to start laying for weeks now. Her comb had got as red as Big Chicken's and a similar size. But day after day there was just the one egg from Big Chicken (except on Sundays when she doesn't lay!?)
A few days ago we were awakened by a strange noise, initially (still half asleep) we thought it was Poppy, but realised it came from outside and the direction of the chicken coop. We didn't manage to track down what was making it until a couple of mornings later when we realised it was Brave Chicken and the sound was starting to evolve in to 'Cockle doodle dooooooOOOOOOOooo'.
This made us wonder... maybe Brave Chicken is actually Brave Rooster. We studied her a bit closer and now her comb is much bigger than Big Chicken's and the wattle under her chin is too and actually she is too. Today when I was feeding them she tried to mount Big Chicken -  who was having none of it. But still it all seems to be adding up to one thing. Brave Chicken is a a boy. Which would also explain why Big Chicken hen pecks the other chickens but not Brave Chicken.
Maybe we will have baby chicken to eat soon. We were just thinking we might get a rooster... although we had been worrying about the noise a bit. We will certainly have to move them from where they are now which is just outside the bedroom window.
