At what age do I stop feeding my chicks starter crumbles?

[Beanbag]

Hello everyone! My oldest chick is going on 5 weeks old and the others are between the ages of 2 weeks to 3 1/2 weeks old. When should I stop feeding them starter crumbles and what type of food do I feed them next?

I feed mine chick starter (unmedicated) until they are at the point of lay (around 18-20 wks) and then switch to a laying pellet.

There also is a 'grower' available, but I just keep them on the chick starter.

You don't want to switch over to a laying pellet/crumble too soon as the extra calcium can be not so good for growing chicks, and growing chicks need extra protein.
