I recently put all my girls on flock raiser as I am raising pullets and they are mixed with my hens. I am providing oyster shell at all times but recently, two of my hens started laying soft shelled eggs. The hens are laying better with the added protein but they are not getting the calcium they need. I gave emergency calcium to one of my hens and she is laying good eggs now so I know its the calcium. I'm at a loss as what to do. Any suggestions?
