yeah i learned it a long while back. those baby fighting chickens, if left unfed or not fed the right (high protein) food will eventually start fighting and tear each other up at 2 weeks old..lols okay maybe more like at a month or two. Its bound to happen but with proper feed and hunger satisfaction, they can go longer until the sibling rivalries start happening, and with the right balance of feed, the worse is they scuffle for a few minutes only..lols once they fully mature, and realize how life really is, that's a different story..seperat ion is a must..lols at least for the males..lols
