Chickens should be given grit when they start eating solid foods, typically around 3-4 weeks old, to aid in digestion and break down food effectively.
Grit is a crucial part of a chicken’s digestive system, yet many backyard chicken keepers overlook its importance. This guide explains exactly when and how to provide grit to ensure your flock stays healthy.
What Is Chicken Grit?
Grit consists of small, hard particles like crushed granite or flint that chickens consume to aid digestion. Unlike oyster shell (which provides calcium for egg production), grit helps grind food in the gizzard since chickens lack teeth.
Types of Grit
- Chick grit: Finely ground for chicks under 8 weeks
- Adult grit: Larger particles for mature chickens
When Do Chickens Need Grit?
Chickens require grit whenever they eat anything besides commercial feed. Here’s the breakdown:
For Chicks
Start offering chick grit at 2-3 weeks old when you begin introducing treats. Before this, chicks eating only starter crumble don’t need grit.
For Adult Chickens
Provide grit if your chickens:
- Free-range (even if they might find natural grit)
- Receive kitchen scraps or treats
- Eat whole grains or scratch
- Forage for greens or insects
How to Offer Grit
Follow these best practices:
Feeding Methods
- Keep in a separate container for free access
- Mix small amounts with feed when first introducing
- Use construction sand as a budget alternative
Quantity Guidelines
| Chicken Age | Grit Type | Amount |
|---|---|---|
| 2-8 weeks | Chick grit | 1 tbsp per 3 chicks weekly |
| 8+ weeks | Adult grit | Free choice in separate dish |
Common Grit Questions Answered
Do Chickens Need Grit With Commercial Feed?
No – if eating only commercial pellets/crumble. However, most backyard flocks get treats, making grit necessary. Learn what kitchen scraps chickens can eat.
Can Chickens Overeat Grit?
Rarely. Chickens self-regulate grit intake. If you notice excessive consumption, limit access and consult a vet.
Is Sand the Same as Grit?
Construction sand (with small pebbles) works similarly. Avoid play sand, which is too fine. Discover why chickens love digging in dirt and sand.
Signs Your Chickens Need Grit
Watch for these indicators:
- Undigested food in droppings
- Decreased appetite
- Lethargy or discomfort
- Weight loss despite eating
Expert Tips for Grit Management
Seasonal considerations:
- Winter: Essential when ground is frozen
- Summer: Free-ranging chickens may find natural grit

Where to Buy Chicken Grit
Purchase grit at:
- Farm supply stores
- Online poultry retailers
- Some pet stores
For homemade options, clean construction sand works well. According to Backyard Chickens, many keepers successfully use this budget alternative.
Grit vs. Oyster Shell
Remember these key differences:
| Grit | Oyster Shell |
|---|---|
| Aids digestion | Provides calcium |
| Needed by all ages when eating non-feed | Only for laying hens |
| Flint or granite based | Crushed oyster shells |
As noted by Audrey’s Little Farm, keeping both available ensures complete chicken nutrition.
