I have 3 laying hens (actually I think they just stopped laying for the season) and a 12 week old pullet in one coop. They both need two different feeds, how do I accomplish this? And when can the pullet start on laying mash? I think if she has it too early, the calcium is bad for her, right? Thanks. p.s. - right now, until I figure out what to do, I just have the "quick-gro" in the feeder and no layer mash. The bigger ones love the quick gro!
