I have an 8 X 10 coop with a 6 X 8 run. I was going to divide up my coop into section but if I dont, I can fit a lot more silkies in my flock. I wanted to know the roo to hen ratio. If I have a dozen silkies, how many nest boxes would I need? If I have a dozen pullets, can I put 2 roosters so all of them would be fertile? I dont know how all of that works quite yet. What are the benefits of flock breeding to pair and trio breedings? I dont know what to do yet. I dont really have room for dividing my coop all up into sections. My parents dont see any reason to divide the coop but they dont know anything about breeding. I know if you breed pairs and trios, you know which parents produce the best offsrping but I dont know if I can do that. Maybe when I am older, I will be able to build a bigger coop and more breeding pens but for now, I will just work with what Ive got.
