WOW! OK...I think my girls are piggies, then. I have eight 3-month old pullets (mixed flock, all heavy breeds), and I use 25 pounds about every three weeks (non-medicated chick starter until they get closer to lay...it is WICKED hot around here right now...I am keeping them on a bit higher protein since their consumption is starting to go down). And this is supplemented by 1.) being in a chicken tractor moved every-other-day to fresh grass/clover, 2.) being allowed to truly free range outside the tractor for 1 - 2 hours daily, and 3.) overflow from the garden (tomatoes, squash, zucchini, lettuce, cabbage, collards, and blackberries). They also get treats (I got a small sack of whole flax seed at an Amish bulk store, and they get freeze-dried meal worms). I gotta tell you, I am actually a bit concerned that one or two of them are UNDER weight...all bones and feathers...but seemingly happy and active. Craziness...maybe I *am* over-feeding...
