Buying Guide
- Medicated vs non-medicated: Medicated feeds include coccidiosis prevention, typically using Amprolium. Consider regional disease risk, flock age, and vet guidance when selecting medicated formulas.
- Protein content: Most medicated starters target 18% protein to support weight gain and muscle growth. Higher protein may be beneficial for very fast-growing breeds, while lower protein can be suitable for smaller birds.
- Format and texture: Crumbles and crumbles-mash formats are common for chicks. Mash can be easier for very young birds or brooder setups, while crumbles reduce waste.
- Other nutrients: Look for prebiotics, probiotics, vitamins, and minerals that bolster immunity, bone development, and gut health, especially in medicated formulas.
- Bag size and availability: Starter feeds come in 5 lb, 6 lb packs or larger 25–25 lb bags. Choose a size that matches the flock size and hatch rate to minimize waste.
- Organic and non-GMO options: If avoiding medications or additives, consider non-medicated, organic feeds. Ensure the feed meets essential nutrient requirements for early growth.
- Brand reliability: Reputable brands with clear labeling for medicated ingredients and nutritional composition help ensure consistent quality and safety for chicks.
- Storage and freshness: Store feed in a cool, dry place, sealed to prevent moisture and pest contamination. Use within a reasonable time to maintain nutrient integrity.
