Ok so today i went out to check on my chickens and i mixed chick starter grower with what i thought was layer.I picked up the bag and all it said was "nutrena poultry feed"and i looked on the back and it wasnt layer because they had layer feed so i looked at ingrentents and it said "calcuim-min4.3"so i was wondering if it was just mixed flock feed but they had it to so is layer and when i introduce my chicks to the flock will it be to much for them PLEASE HELP
