🌽 Carbohydrates

What Carbohydrates Does

Carbohydrates are the primary energy source for chickens, providing the glucose that fuels all daily activities from foraging to egg production. Grains like corn, wheat, barley, and oats form the carbohydrate backbone of virtually all commercial poultry feeds. The energy from carbohydrates powers muscle movement, maintains body temperature (especially important for birds in cold climates), and fuels the metabolically demanding process of forming an egg every 25 hours.

Chickens are efficient at digesting simple starches from grains, but they handle complex carbohydrates differently depending on the type. Simple sugars and cooked starches are absorbed quickly in the small intestine, while non-starch polysaccharides (found in barley, rye, and wheat bran) can create a viscous gel in the gut that actually impairs nutrient absorption. This is why some feeds include enzymes like xylanase and beta-glucanase to break down these anti-nutritive carbohydrates.

Excess carbohydrates beyond energy needs are converted to fat and stored as body reserves. This is a useful adaptation for wild birds facing food scarcity, but in well-fed backyard flocks it can lead to obesity and fatty liver syndrome — especially in breeds that are already prone to weight gain. The balance between energy-providing carbohydrates and other nutrients like protein is important for maintaining healthy body condition.

How Much?

Carbohydrates typically make up about 55 to 65% of a standard layer feed diet, mostly from corn and wheat. No specific supplementation is needed — the concern is usually too much rather than too little. Keep scratch grains and carbohydrate-heavy treats like bread, pasta, and rice to no more than 10% of total intake to avoid diluting the balanced nutrition in the layer feed.
