Ok. I have a mill near me where the feed in crumble in 50 pound bags for 9.50. It is a corn meal based then they add all the extra stuff. I just switched to Purina Layena to see if there would be a difference. Well one week later, out of 36 laying hens the eggs are very less and less every day. It seems like the chickens eat more as if the feed is not filling them up. I know Purina has lots of stuff in it but is it full of fillers that do not keep them full? It seems the feed from the mill last much longer...
