We have them in the same run with a chicken wire separation right now. Chicks are 3 weeks old. Older birds are 13 weeks old. All are bantams. Of the older birds, 2 are male, 1 female. All younger ones are female. - Do you think it will be any harder or easier to mix groups since the older ones are mostly male? - How long would you wait before putting them together? - Do you think they will ever be one flock since they are only 10 weeks apart? Or will they probably just coexist seperately. I was hoping the roos might help protect the babies one day. -Do roos get involved in pecking order? Or is that just a hen thing. Thanks for any and all advice!
