The only extra thing in layer feed in extra calcium, you can feed grower and get oyster shell to throw out for your layers. They'll pick out what they need. Layer feed has ho hum nutrition.I have birds in various stages mixed in 3 different pens. I was mixing half and half grower feed and layer feed to ensure layers got some extra protein (with their necessary laying vitamins/minerals) and chicks enough protein and other nutrients to grow. I can switch to only chick feed for this guy, but the others will probably need to stick to the 50/50 mix…
