When it comes to babies and layer feed, how much is too much? Between the big girls and them I don't think they're getting alot, the babies food is unaccessable to the hens so they're getting all they need. The calcium percentage is 3.5% min. 4.0% max on the layer feed, the grower feed is 0.9% min. 1.0% max I I keep my hens free ranging for about 7-8 hours a day then the remainder they're in with the little ones, I put their layer feed in and of course the babies are drawn to that feeder I've put it up higher, but at this age they're masters at flying and easily get into anything, it's easier for the babies to reach a higher feeder than my hens .
