ok, I have a pen with 4 roosters...and I was wanting to get them Rooster Booster. So, off I go to the feed store. Yeah well.....I THOUGHT I was going to get some Rooster Booster. The guy looked at me like I had 3 heads when I asked for it!! Who makes it....whats the protien %??? He said if I can get a manufacturer name, he MIGHT be able to get it. HELP!!
