Feed chickens about 10% of their diet with cracked corn, typically 1/4 to 1/2 cup per bird daily, depending on their size and activity level.
Cracked corn can be a valuable supplement to your chickens’ diet when used correctly. This guide covers everything you need to know about feeding cracked corn to your flock, including proper amounts, benefits, risks, and alternatives.
Recommended Cracked Corn Amounts for Chickens
The general rule for feeding cracked corn is to limit it to no more than 10% of your chickens’ total daily diet. Here are specific recommendations:
| Chicken Type | Daily Amount | Notes |
|---|---|---|
| Adult Laying Hens | 1/4 lb per 10 chickens | Mix with complete feed |
| Meat Birds | 1/2 lb per 10 chickens | Good for weight gain |
| Bantams | 1/8 lb per 10 chickens | Adjust for smaller size |
Why the 10% Limit?
Cracked corn contains only 9.5% protein compared to the 16-18% protein chickens need in their diet. Too much corn can lead to nutritional deficiencies and obesity. Underweight chickens might benefit from slightly more corn, while overweight birds should get less.
Best Times to Feed Cracked Corn
Winter Feeding
Cracked corn is excellent in cold weather because:
- Digesting corn generates body heat
- Helps maintain fat reserves
- Provides quick energy in cold temperatures
Evening Treat
Feeding corn before roosting helps keep chickens warm overnight. This is especially helpful for cold-sensitive breeds like Silkies.
How to Feed Cracked Corn Properly
Mixing Methods
- Combine with complete feed (90% feed to 10% corn)
- Scatter in run to encourage foraging
- Mix with other treats like oats or sunflower seeds
What to Avoid
- Never feed moldy corn
- Don’t replace main feed with corn
- Avoid feeding corn exclusively in summer
Nutritional Profile of Cracked Corn
Understanding what cracked corn provides (and lacks) helps explain feeding guidelines:
| Nutrient | Amount | Chicken Requirement |
|---|---|---|
| Protein | 9.5% | 16-18% |
| Fat | 4% | 5-6% |
| Calcium | 0.02% | 3.5-4% |
Cost-Saving Alternatives to Cracked Corn
If you’re using corn to reduce feed costs, consider these more nutritious options:
Fermented Feed
Fermenting regular feed increases nutrient absorption, meaning chickens eat less. According to Backyard Chickens, fermentation can reduce feed costs by 30-50%.
Free Ranging
Allowing chickens to forage can cut feed costs by up to 2/3 while providing better nutrition than corn.
Kitchen Scraps
Vegetable peels, leftover grains, and protein scraps can supplement feed. Avoid salty, sugary, or spoiled foods.
Special Considerations
Breed Differences
Heavy breeds like Jersey Giants can handle slightly more corn than lighter breeds. Adjust amounts based on your chickens’ condition.
Age Factors
Chicks under 16 weeks shouldn’t eat cracked corn. Wait until after they start laying to introduce corn treats.
Health Conditions
Chickens with weight issues, egg binding, or fatty liver disease should avoid corn. Always consult a vet for special dietary needs.
Common Questions About Cracked Corn
Does Corn Make Egg Yolks Darker?
While corn can enhance yolk color, dark leafy greens and marigold petals are more effective. The Dine a Chook blog notes many factors influence yolk color.
Can Chickens Eat Whole Corn?
Yes, but cracked corn is easier to digest. Whole corn is fine for adult birds but should be limited to occasional treats.
Is Cracked Corn the Same as Chicken Scratch?
No. Scratch mixes contain corn but also other grains. Plain cracked corn is more concentrated and should be fed more carefully.
