Chick Diet: First 8 Weeks

By The Coop Team ยท Updated July 3, 2026

Quick answer

During the first 8 weeks, feed chicks starter crumble with 18-20% protein at all times. Provide fresh water and fine chick grit after 2 weeks. Treats can start after 2 weeks but should be under 5% of their intake until then. Switch to grower feed at 8 weeks.

Weeks 0-8: Chick Starter

Provide chick starter crumble with 18-20% protein in front of the chicks at all times. Use medicated starter (with amprolium) if the chicks were not vaccinated for coccidiosis at the hatchery. If they were vaccinated, use non-medicated starter, as medicated feed cancels the vaccine.

Ensure fresh water is always available in a shallow chick waterer. For the first week, place clean pebbles in the trough to prevent drowning.

Introducing Grit and Treats

Offer fine chick grit free choice once they receive any treat other than pure starter. Do not give treats before 2 weeks, as they need to imprint on real feed.

From weeks 2-8, you may introduce treats, but keep them tiny and under 5% of their intake. Suitable treats include:

  • Scrambled egg
  • Chopped hardboiled egg
  • Small bits of leafy greens
  • Mealworms
  • Plain yogurt in a smear

Avoid layer feed entirely, as the calcium load can damage developing kidneys.

Transitioning to Grower Feed

At 8 weeks, switch to grower feed with 16-18% protein, or continue with starter through week 18 if using a starter/grower combo bag.

At 18-20 weeks, or when the first egg appears, switch layer-age pullets to layer feed. Alternatively, move the whole flock to all-flock feed and provide a separate oyster shell dish.
