I have about seven 5 week old roos that I want to put out with my other chickens. I have 4 roos in my flock right now, 2 are 18 weeks, and 2 are only 10. I don't want to keep the 7 new roos out there permanently, just until their coop is vacated by the meat chickens currently using it (which will be in about 3 weeks). Can I do this?? Do I need to worry about the older roos killing the baby roos??? I intro'd 14 new 5 week old hens the other day, and everything's fine, no major pecking, and the older chickens are letting the baby hens eat and drink and everything. I just don't want my baby roos getting attacked and killed because of their gender. Thanks!!!!
