Chicken Grit

Chickens don’t have teeth—so grit is essential. It allows birds to “chew” & break down their feed naturally, improving digestion and nutrient absorption for better health & consistent egg production. Mile Four Grit is made from 100% natural quartzite, a hard, pure rock that helps grind food efficiently in the gizzard. With no additives or fillers, it’s a simple, effective way to support strong shells, healthy digestion, & happy chickens.

Key Features:

• Two Grit Sizes: Starter Grit for chicks 0–8 weeks; Layer & Grower Grit for birds 8+ weeks.
• Essential for Digestion: Helps chickens process feed efficiently & absorb nutrients for optimal health.
• Supports Egg Production: Promotes consistent laying & stronger eggshells through improved nutrient absorption.
• Natural & Safe: 100% quartzite grit with no chemicals, dyes, or fillers—just pure, effective rock.

• Starter Feed
  Begin with 100% Starter feed, which is high in protein to support early development. Around Week 7, start mixing 75% Starter feed + 25% Grower feed for a few days. Gradually adjust the ratio, reaching 100% Grower feed by Week 9.

• Grower Feed
  Keep pullets on 100% Grower feed to support muscle growth & steady development. At Weeks 19-20, introduce 75% Grower feed + 25% Layer feed to help their bodies adjust to increased calcium levels. Increase the Layer feed portion until reaching 100% Layer feed by Week 21.

• Layer Feed
  Once chickens begin laying eggs, switch to 100% Layer feed, which contains added calcium for strong eggshells. Supplemental Grit & Oyster Shell can further support shell strength.

• Oyster Shell & Grit
  Serve Oyster Shell and Grit in separate small containers, placed near the feeder but never mixed into the feed. Chickens will eat Grit as needed to aid digestion & Oyster Shell to boost calcium for stronger eggs. Refill weekly & keep both dry & accessible at all times.

For a smooth feed transition, adjust the mix gradually, monitoring flock’s appetite & digestion. A balanced chicken diet at every stage ensures healthy growth, optimal egg production, & strong immune function.
