I have a flock of 23 RIR (22hens, 1roo) and have hatched 34 of their offspring to keep for eggs... they are 8 weeks old now and it "appears" that there are 11 cockerels and 23 pullets... I want to have fertile eggs but of course mating the girls with their brothers is not a great idea and I know I need to get a couple of unrelated cockerels to put with them. What I need to know is if any of you have or know what is the best way to go... wait and get grown roos later... buy a few male chicks and put them in when they are out of the brooder... will they get picked on if they are younger than the pullets? How is the best way to go about this introduction of new blood to my flock?
