Chickens need a balanced layer or grower feed as their base, supplemented with calcium (oyster shell), grit for digestion, and fresh treats. Protein requirements vary by age and purpose — layers need more calcium, chicks need higher protein.

Selenium is a trace mineral that forms the core of glutathione peroxidase — one of the body's most important antioxidant enzymes — protecting cells from …
Sodium is an essential electrolyte that maintains fluid balance, supports nerve impulse transmission, and helps transport nutrients across cell membranes. For laying hens, sodium plays …
Potassium is one of the most abundant minerals in your chicken's body and is essential for virtually every cell function. It maintains the electrical gradient …
Copper is a trace mineral essential for iron metabolism — without adequate copper, your hen cannot properly mobilize iron from her stores to build hemoglobin, …
Vitamin E is your flock's antioxidant shield, protecting cell membranes from the oxidative damage that comes with the intense metabolic demands of daily egg production. …
Vitamin K is the clotting vitamin — without it, even a small wound or internal bruise could lead to dangerous uncontrolled bleeding. It activates the …
Thiamine (Vitamin B1) is essential for converting carbohydrates into usable energy and maintaining healthy nervous system function. It acts as a coenzyme in the metabolic …
Riboflavin (Vitamin B2) is one of the most critical B vitamins for poultry, and its deficiency produces one of the most recognizable nutritional diseases in …
Niacin (Vitamin B3) is crucial for energy metabolism, converting the carbohydrates, fats, and proteins in feed into usable cellular energy through the coenzymes NAD and …
Pantothenic acid (Vitamin B5) is a component of coenzyme A, one of the most important molecules in all of cellular metabolism. Coenzyme A is involved …
Pyridoxine (Vitamin B6) is central to amino acid metabolism — it helps the body process and rearrange amino acids from dietary protein into the specific …
Folate (Vitamin B9) is essential for every process in the hen's body that involves rapid cell division — and in a laying hen, that includes …
Vitamin B12 (cobalamin) is essential for red blood cell formation, nervous system maintenance, and DNA synthesis. It works closely with folate in the metabolic pathways …
Choline is sometimes grouped with the B vitamins, though technically it is not one. It serves three essential functions in your hen's body: it is …
Chloride works alongside sodium to maintain fluid balance and acid-base equilibrium throughout the hen's body. It is also a key component of hydrochloric acid (HCl) …
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, …
Omega-6 fatty acids, particularly linoleic acid, are essential fats that chickens cannot synthesize and must obtain from their diet. They are structural components of cell …
Iodine is a trace mineral essential for the production of thyroid hormones (T3 and T4), which regulate metabolic rate, body temperature, and the growth cycles …
Carotenoids are the pigments responsible for the rich, deep orange yolks that backyard chicken keepers are so proud of — and that store-bought eggs rarely …
Probiotics are live beneficial microorganisms that support the complex ecosystem of bacteria living in your chicken's digestive tract, particularly the ceca. A healthy chicken gut …
Methionine is the first limiting amino acid in poultry diets, meaning it is the one most likely to run short before any other amino acid. …
Lysine is the second limiting amino acid in poultry diets (after methionine), meaning it is the next most likely to run short in a grain-based …
Tryptophan is an essential amino acid with a fascinating dual role in chicken biology. First, it is a standard building block for protein synthesis, needed …
Taurine is a sulfur-containing amino acid that, unlike most amino acids, is not incorporated into proteins. Instead it functions as a free amino acid with …
Biotin (Vitamin B7) is essential for healthy skin, feathers, and claws because it supports keratin production and the fatty acid synthesis that maintains skin barrier …
