The recommendation from the local feed store is to keep everyone on BlueSeal Gamebird stater/grower. This has 22% protein and 4% fat. The older chickens are 10 months old and laying really well. (I provide oyster shell free choice) The younger chickens and ducks are between 17 and 21 weeks. One RIR and one Khaki Campbell have started laying. I am wondering if their diet is wrong. My other option is BlueSeal Growe-Cal. This has 15% protein abd 2.5% fat. Should I switch them or is the higher protein, higher fat ok?
