Why Buy
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.
Instructions for Use
Leave grit out at all times in a separate dish or feeder, never mixed into feed. Chickens/chicks eat only as much as they need and won't overeat.
As a rough guide, layer and grower birds (8+ weeks) go through about 1 lb. per bird per month, while starter chicks (0-8 weeks) use closer to a quarter pound each; actual intake varies by breed, season, and how much the flock free-ranges.
Store in a cool, dry place.
