The ones we picked up were put out with our yard birds. At first they did OK except they didnt fly well and we wrote that off to having been raised in a large scale chicken house. But as they got bigger they had a harder time getting around. One broke a foot just jumping down from a low roost and then had a really rough time of it. Their bodies keep growing but their bones only go so far. then one morning theyd be laying flat on their back with their feet in the air like a cartoon the only birds weve had to do that.I wonder if that's because stateside varieties are bred for their breast meat, so they're top-heavy. Whereas outside of the UK and North America, it's the legs that are prized, so they're bottom heavy.
