my hubby being so helpful went to the feed store and brought home 3 -50# bags of finisher feed for the newly laying hens...he already opened a bag and filled the feeder a few days ago .. then i saw the bag.. ooops wrong stuff.. what is it missing that my hens need supplemented so we can finish off the opened bag? i have grit and calcium in feeder tubes seperate from feed bucket.. they free range a couple of hours each evening
