Is it a better idea to have two breeding pens for each breed of chicken you want to breed, or would one be ok? I want so many haha I plan to have one roo covering 10 hens In each breeding pen. It will be a 5x12 coop and a 5x40 run. I want to have 16 of these for different breeds of chicken and ducks(5 ducks 1 drake) then two breeds of Turkey that will have 10x40 runs with 5 hens and 1 Tom. Then there would be a 10x12 supply/brooder/incubator room, and a 10x12 rabbit colony attached to a 10x40 run as well. These are all just big dreams but better to plan now on what I would like to do.I was originally going to have two pens for each breed, but if I could I would like to have more breeds and color variants instead.
That depends on if you end up breeding for quantity or quality. More means more. Less means easier to control outcomes in breedings.
