What is the protein percentage of the feed? I use Purina Flock Raiser 20% protein. I have also fed Purina Layer, Nutrena Layer, both 16% protein. As long as you’re not diluting your protein by feeding a lot of scratch, corn, or other treats, you are probably doing okay. But you can bump her protein up to 20% for awhile just to see if it makes a difference. Just feed 90% of their diet as chicken food.
