Just curious, but do you all know the difference in adults? I was always told it's impossible to tell who is who, but I found that wasn't the case. I get really into my animals and tend to find the subtle differences.
My theory is:
Hens have a larger chest cavity, their "boom sack" (we called it that because the thumping they do sounds like nothing but bass from the boom box) is larger and they prance with it filled out. They make the booming noises. They are VERY aggressive and tend to fight more.
Cocks are smaller. They make a sound that sounds almost like a pig grunting. Their chest is usually flat and does not fluff up with air.
I have not seen a difference in the feathers or facial features, though and never attempted to vent sex - this istoo intrusive and, well, rude, lol.
I always got mine as adults and never had the long wait. The only time I had chicks they were for meat production so they never got old enough for me to wonder what they were.
Anyway, that's how I learned on adult birds.
