this guy down the road from me was selling his cabinet incubator, so i went over there to purchase it and checked out some of his chickens. he actually had grown cornish X on his property. i think the rooster was wide as he was tall. i was amazed they were alive. they actually forage AND mate. he said he just processed some of the roosters but i saw about 10 of them waddling around and the roos had spurs. he said they were around a year old!
