My 11 pullets are 8 weeks old today. The Chick Starter feed instructions are to feed up to 8 weeks old, then switch to a Grower feed. I went to the feed store today and picked up a "Grower/Finisher" feed but was surprised to see the protein content of the Grower at 15%. Isn't that a bit low? From my research it seems you start out with higher protein, then back off a bit to allow them to grow up without growing too fast, then switch to layer ration when they actually start to lay. I was planning on mixing the remaining Starter with the Grower until I use up the Starter. They are living in a chicken tractor for the summer with limited free-ranging (evenings and weekends) and kitchen scraps (including hard-boiled egg yolks from a cholesterol-fearing relative who saves them for us). Any help would be great -- These are my first chickens, and I acknowledge that I have a lot yet to learn!
