Rhode Island Red chickens require balanced nutrition that varies throughout their lifecycle, beginning with chick starter feed containing 18-20% protein from hatch until approximately 8 weeks of age. This high-protein starter supports the rapid growth and development essential during early life stages when chicks can double their weight within days. Chick starter is available in medicated forms containing coccidiostats to prevent coccidiosis, or non-medicated versions for vaccinated chicks or those in very clean conditions. Fresh, clean water must be available 24/7 from day one, as even brief water deprivation severely impacts chick health and development.
From 8 weeks until point of lay (around 18-20 weeks for Rhode Island Reds), transition to grower feed containing 16-18% protein. This moderate protein level supports continued healthy development and body frame growth without the excessive protein that could cause too-rapid maturation. Some keepers use all-flock feed during this period, especially when managing mixed-age flocks, though grower-specific formulations optimize pullet development. As pullets approach laying age and combs begin reddening, gradually transition to layer feed over 7-10 days by mixing increasing proportions of layer feed with decreasing grower feed.
Once hens begin laying (typically 18-20 weeks for Rhode Island Reds, sometimes as early as 16-17 weeks for production strains), switch completely to layer feed containing 16-17% protein and crucially, 3.5-4% calcium essential for eggshell formation. Layer feed comes in pellet, crumble, and mash forms; most keepers find pellets reduce waste while crumbles work well for all ages. Provide layer feed free-choice in appropriate feeders, allowing hens to regulate intake based on their production demands. A Rhode Island Red hen in peak production needs approximately 1/4 to 1/3 pound of feed daily, though free-ranging birds typically consume less commercial feed while maintaining or even improving production.
Critically important: provide supplemental calcium through crushed oyster shells or thoroughly crushed and baked eggshells offered free-choice in a separate container from feed. While layer feed contains calcium, many hensβespecially heavy layers like Rhode Island Redsβneed additional calcium for consistently strong shells, particularly during peak production or hot weather when calcium absorption can decrease. Hens instinctively regulate their calcium intake, consuming more when needed for shell production. Never mix calcium supplements directly into feed as excess calcium harms non-laying birds including roosters and young pullets; free-choice feeding allows each bird to consume what it requires.
Rhode Island Reds are exceptional foragers who enthusiastically and efficiently seek insects, worms, greens, seeds, and other natural foods throughout their environment. Their foraging provides high-quality protein from insects, essential vitamins and pigments from greens, and valuable mental and physical enrichment while substantially reducing commercial feed costs. Free-ranging Rhode Island Red flocks may reduce feed consumption by 25-40% during growing seasons, though layer feed should always remain available free-choice to ensure complete nutrition. In runs or during winter when foraging is limited, supplement with fresh greens like lettuce, kale, cabbage, or sprouted grains, and offer scratch grains or cracked corn as treats but limiting to no more than 10% of total diet to avoid nutritional imbalances.
Clean, fresh water must be available at all times without exception, as water intake directly affects egg production, feed digestion, body temperature regulation, and overall health. Laying hens drink 1.5-2 times as much water as they consume feed by weight, with Rhode Island Red hens in production drinking 1-2 cups or more daily depending on temperature and production level. Water deprivation for even a few hours can halt egg production for several days. During winter, prevent water from freezing using heated waterers or by refreshing water multiple times throughout the day. In summer heat, provide water in shaded areas, consider multiple water stations, and monitor closely as consumption can double or triple during extreme heat.
Insoluble grit (granite or flint chips) is essential for chickens without access to natural small stones and pebbles, collecting in the gizzard where it grinds food particles mechanically. Provide grit free-choice in a separate container, especially crucial for birds eating whole grains, scratch, or without outdoor access to natural grit sources. Oyster shell serves as soluble calcium grit but does not replace insoluble grit for digestion. Treats should be limited to 10% or less of total diet; healthy options include mealworms for protein, fresh vegetables and fruits, limited scratch grains, and kitchen scraps. Strictly avoid toxic foods including chocolate, avocado, raw or dried beans, moldy or spoiled items, and anything high in salt or sugar.
