Mutt if you have birds molting or have a cold winter weather the All Flock Raiser is your best choice. The extra protien helps feathers grow faster
You have me thinking (rarity) I have all pullets under 1 yr. On grower w/ oyster shell 10/15 laying now. My youngert 5 are only a week or 2 from laying. I was going to switch to layer. Winter here is not at all cold. We can dip below 30 rarely, but...we have sudden drops, and my hens are NOT acclimated below 60. We're in for a historically wet winter. They predict 200% of normal rainfall. Think I'd be better to switch to Flock Raiser for added protein?
