I'm worried about that myself. I have some 7 week olds that do OK for part of the day, but I separate them for most of it. I have some 20 week olds that I also have to separate from the 10 months olds. The 20 weekers are starting to accept the 7 week olds but then I have some week old chicks that will eventually need to be integrated too.
I'm thinking I'm not going to get any more little ones until I have a number of separate pens.
