We have been offered a rooster that is from last years hatch. I have BSL and either a barred rock or australorp. They are 6 and 9 weeks old. In another thread I started the one person that answered sad it is not a good idea to add one that old with all the youngsters. So how is the best way to do it? Do I look for a roo around the same age? I only want one so if I have to isolate him he would be alone. I also want to know what crosses produce what. I will keep rotating my flock every 18 months to 2 years. I will be keeping heavy breed brown egg layers. I live in a cold winter climate. So can someone give me some guidance as to what would be the breeds to have with what. I hope this is making sense. Now since I have black colored birds I will get lighter colored or more laced or barred chicks next spring so I will try to keep alternating some. IF someone can figure out what I am trying to ask I would appreciate some help here. I would love to have some few chicks now and then.
