FEED THE BIRD IN FRONT OF YOU
Species, age, laying status and purpose determine the ration.
Record the feed name, species and life stage on the label, lot number, purchase date, amount offered and every supplement or treat. Review problems with a poultry-experienced veterinarian or qualified poultry nutrition professional.

01 · DAILY FOUNDATION
Match the complete feed to species and life stage
- Use a commercially complete poultry feed labeled for the exact species and stage whenever possible.
- Starter, grower, maintenance, breeder, layer and meat-bird rations are not interchangeable.
- Provide continuous access to clean water; birds reduce feed intake quickly when water is unavailable.
- Keep feeders sheltered from rain, rodents, wild birds and fecal contamination.
- Change rations gradually while monitoring intake, droppings and production.
02 · SPECIES DIFFERENCES
Do not feed every flock from one bag
| Group | Feeding emphasis | Important caution |
|---|---|---|
| Chicks and growing chickens | Complete starter/grower matched to age and purpose | Layer feed can provide inappropriate calcium to growing birds |
| Laying hens | Complete layer ration with adequate calcium and constant water | Scratch and treats dilute the ration |
| Ducks and geese | Waterfowl-appropriate feed, abundant water and grazing where suitable | Growing ducks may have different niacin needs than chicks |
| Turkeys | Turkey/gamebird ration matched to growth stage | Chicken feed may not meet growth needs |
| Quail and gamebirds | Gamebird/quail ration matched to age and laying status | Particle size, crowding and access matter |
Important: Mixed-species flocks often require separate feeding areas or carefully selected plans so each bird receives the correct ration.
03 · WATER & FEED HYGIENE
Water failure becomes a feeding emergency
- Check water flow, cleanliness and temperature at least daily and more often during heat or freezing weather.
- Use enough drinking stations that timid birds cannot be excluded.
- Waterfowl need water deep enough for normal bill and nostril cleaning, managed so litter does not remain saturated.
- Discard moldy, wet, insect-infested or rancid feed.
- Store feed cool, dry and sealed; buy amounts that remain fresh before nutrient quality declines.
04 · GRIT, CALCIUM, TREATS & PASTURE
Extras have specific jobs—not automatic benefits
- Insoluble grit helps birds grind certain whole foods; it is not the same as soluble oyster shell or another calcium source.
- Offer supplemental calcium separately only when appropriate for laying birds and the overall ration.
- Keep treats and scratch grain small enough that complete feed remains the clear majority of intake.
- Pasture and insects provide behavior and variety but are difficult to balance as the sole ration.
- Avoid moldy food, avocado, chocolate, caffeine, alcohol, very salty foods and unknown toxic plants.
Important: Do not add vitamins, electrolytes, calcium or medications routinely without a defined need; excesses and interactions can also cause harm.
05 · MONITORING
Track the flock and the individual
- Body condition and keel-muscle coverage
- Growth rate, mature weight and feed disappearance
- Egg number, shell quality and hatchability when relevant
- Droppings, water intake and litter moisture
- Whether timid, small, injured or different-species birds reach feed and water
06 · COMMON NUTRITION-RELATED PROBLEMS
Look beyond the feed bag
- Poor growth or feathering from an incorrect ration, competition, disease or parasites
- Thin shells or skeletal weakness involving calcium, phosphorus, vitamin D, laying intensity or disease
- Obesity and fatty-liver risk from excessive energy and treats
- Wet litter from water management, salt, disease or inappropriate ingredients
- Feed refusal caused by spoilage, water failure, heat stress, toxins or illness
Important: Nutrition signs overlap with infectious, parasitic, reproductive and environmental disease. Diagnosis should come before treatment.
07 · WHEN TO CALL
A sudden feeding change can signal a flock emergency
- One bird stops eating and becomes quiet, weak or unable to stand
- Several birds reduce intake or water use together
- Sudden deaths, neurologic signs or breathing difficulty
- Crop remains abnormally enlarged, foul-smelling or does not empty
- Suspected mold, toxin, feed-mixing error, contaminated water or equipment failure
Important: Save the feed bag and lot information. Do not discard all evidence, medicate the flock blindly or move birds off the property until the veterinarian or animal-health authority advises you.
