Some of these chick foods are confusing! I was at a farm supply store this weekend getting some stuff for the garden and decided to take a look at the feeders/waters I'll need for the chicks. I got one of each, and then decided, since this store is a bit of a drive, to pick up some chick starter. They had a convenient 5Lb bag of medicated starter crumbles (by Manna Pro), so I picked it up knowing it was what I needed to start with. (Don't need 50lbs for 4 chicks!) The instructions say to feed from 0-8 weeks. But Manna Pro doesn't make anything to give after that! Is that when I should look to switch to a finisher, or a starter-grower, or what? Also, this particular brand of starter crumbles is only 18% protein. I looked at what TSC offers, and their starter is 24%, or a starter/grower combo is 20%. Should I use something else? Why such a difference in the protein content among starters? is 18% enough? The Manna-Pro starter crumbles have some small chunks in it- is that ok? It doesn't say to feed with grit, but I've seen chick food that is nearly powdery, this is not. Am I just thinking too much? Also, for those with small backyard flocks, how much starter do I need for four chicks? I know I might need additional 5lb. Bags, but 50 Lb. seems a bit excessive, right?
