Chick feed to grower feed?

[The10 bundles of joy]

Hey, I’m wondering when I should change from chick starter to grower feed? My chickens are 5 weeks old right now

Directions are usually on the tag at bottom of bag. It's usually 6 to 8 weeks of age.
If it's 18 to 20% Protein, you can feed till 18 weeks or the first egg.
I feed a combo Start and Grow/Starter-Grower feed.
I feed Medicated till 10 weeks, then when bag is empty I switch to a Non-medicated Starter-grower or a All-Flock Crumble. GC

"When you run out of starter feed" is the time I'd switch over. No reason to have unused starter feed sitting around.
