Integrating Young Birds

[Alek]

I have 5 5 week old chicks & 7 7 week old chicks. I've put them together in a space outside(the weather is pretty warm), & they've been pecking each other but I've been raising chickens for 5-6 years & know its pretty normal for the to peck each other, but I've never integrated younger birds together, only adults & chicks. They do tend to be staying in respective corners of the pen & not really interested in being around each other much. So when should I be concerned about how much they peck each other & separate them?

Same as for older birds....bleeding, pinned down and beaten, not able to eat and drink.
