We just got what we thought was grower mash (actually what we asked for) and when we arrived back home realized they gave us Purina starter grower crumble (non medicated). Too far to return the 100lbs of feed so we started using it and the chicks (35 of them) don't seem to like it. Will they get used to it? Before they were eating like pigs. we were going through 50 lbs a week.
