The breeds I've decided on for meat birds I'm thinking now might be harmed by to much protein after reading these comments. Jersey Giants and Langshans. I was thinking back to when I first became a BYC member and someone on the upstate NY thread posted pics of her new great dane puppy. I commented that I had had a boxer and fed him high protein large breed Eukanuba (pre wife and fam days I survived on ramen noodles and beer Lol) and he ended up ten pounds heavier and much more filled out than his two brothers that my friends had and fed cheap dog food. She said it was the worst thing you could do to a great dane, they needed a low protein diet, a special diet to help them grow slow, or they have all sorts of health issues. I looked it up and she was right. Now I'm thinking these giant birds might need the same idea being they take a long time to mature??
