Debbi, either one would work, but I have my feed mixed up at the mill and ad lots add meat scraps . If you feed around a 22 % protein level everything else will basically take care of its self. I use a lot of soy bean meal here to increase the protein level. In the past I have experimented quite a bit here with the fowl in condition pens. With the Large fowl you want the extra Protein so you can get the extra muscle bulk.Don, What do you use to increase the fat content of the feed? Flax, sunflower, something of that nature?
