Hi everyone, I am fairly new to raising chickens. Fortunately my neighbor is a breeder. He breeds to the breed standard, shows his birds, and also raises more rare breeds. Currently I have 5 barred rocks, 4 of which are roosters, this group is 7 months old. Roos are all kept separate. I also have five 8 weeks old javas, three of which are roosters. I plan on giving two of those roos back to the breeder. I would like to get more pullets the same age as my javas but I would like to know if I can do this and mix the new ones with the current 8 week old javas. The javas are soon going to have their own coop and run so I thought this would be a good time to find more pullets the same age and mix them. Can I do this, even if it is a different breed the same age? I haven't seen too much info on this part of managing your flock either online or in any books I have. Does anyone have any thoughts on this? I would appreciate it.
