Ha ha! Now I may not know much about keeping chickens yet (save what you good folk and my books have told me) but I certainly know about Genetics! (I am a Biologist).......I actually teach A Level students about chicken genetics!!! So, here goes.........you breed RIR and Sussex to get Warren you say? Then you wonder what will happen if you breed a Warren hen and Warren cock? Well, you could end up with a right array of "Heinz" chicks! No guarantee......some will be like either parent and some will be more Warren like.
Not sure about the dodgy cockerell,.......I used to keep pigeons (retired racers, to prevent them being "necked", bit like rescuing ex-bats!)......one time, a male turned up and decided to move in with us. We contacted his owner who didn't want him back so we kept him. But he had no mate. Everyone else was paired up. He turned gay for a while, then when we did get him a lady friend, he crouched down to her. She was very confused. So thus followed me having to teach him about the birds and the bees. I kept lifting him on top of her when she crouched down (he just used to look confused when she did). In the end, he worked it out and they lived a long and happy life together. I hope this poor cockerell has a similarly happy life eventually. (Though all those women is probably enough to scare any bloke, I would guess.......talk about hen pecked!! :roll: )
