When can I put my chicks on all pourpose feed instead of chick starter?
Hens should go onto layer when they start laying. Cockerels should move to grower but it is hard to say exactly when because of the different brands. Some sell starter\grower and some make them both the same but make the crumbles smaller for the starter.
Read the instructions for the feed you are using.
Remember, Rooster are not supposed to have as much calcium as is in most layer feeds.
