So, I will be starting this year on actively breeding to standard on a couple breeds. When beginning, how many should I be looking to hatch yearly to give me the best to select from? We have 6 breeder pens (8x22ft ea.) and a large run (approx. 20x60ft. Planning to use for growouts) in the works. We have two brooders planned but unsure on size they should be. Recommendations?
