I have 8 hens , 1 rooster and 4 bbb turkeys. Currently they are on purina flock raiser, 5 grain scratch, lots of veggie scraps and they free range half the day. My hens started laying a couple weeks ago. I would like to move them to purina laying feed. I am wondering if it is safe for my turkeys. They are about 5 months old. Flock raiser is 20% protein. I believe the purina laying feed is 18% protein
