So I have been feeding my flock chick medicated starter from three days old to six weeks. When they turn six weeks old I was on vacation and my pet sitter bought the multi flock chicken feed. Which is also a sort of starter for Chicken 0 to 8 weeks old. When they get around eight weeks old I am going to switch them to a grower feed. I think I’m going to combine the grower feed and the multi flock feed 50-50. My only problem is the feed store that is closest to me is a blue seal. The grower they have is the grow and show. It says it is 15% protein which seems a little low for a grower feed? Is this just a dumb concern or what should I do?
