Here awhile back i asked if anyone knew about how much BOSS to feed 13 RIR's. I have read all over the place a handful or two here or there but never a handful =how many birds. So i posed the question awhile back and again got the same answer from several hand fulls to a handful per bird. Well lets just say a handful per bird is a good ratio if you want to tar cracks in your pavement! Although i have to say i got 12 eggs out of those 13 RIR's that day, first time ever for that many since i acquired them.
