Feeding laying hens: protein is only one number
An everyday complete layer feed often contains around 16-18% crude protein, but this is a broad label-reading range, not a custom formulation. Commercial phase diets can be higher, and daily intake affects the nutrients a bird actually receives.
Read beyond the headline
Check the intended life stage, calcium, energy information where available, feeding directions and freshness. Lysine and methionine balance also matters. Two feeds with the same crude protein are not necessarily interchangeable.
Check what is consumed
Large amounts of grain, scraps or treats dilute the complete ration. Selective eating can leave nutrient-rich fines in the feeder. Measure feed used and look for waste rather than assuming the full mix reaches every hen.
Match the flock
Body size, temperature, egg output and condition affect needs. Heavy heritage birds should not be fed solely by a consumption chart for small commercial hybrids. Keep water available and obtain nutrition advice for a home-mixed ration.
Next step: photograph your feed label and record a week's use. This is more useful than choosing the bag with the highest protein percentage.
Other life stages
Chicks commonly use a complete starter around 18-20% protein; growers commonly 16-18%, and developers around 15-16% in programmes that use a separate developer. These are orientation ranges, not a recipe. Follow your feed label for transition ages.
Breeder diets are product-specific, often around 17-18% in complete feeds. Nonlaying adults need a suitable maintenance/all-flock plan based on condition and actual laying status. A permanently retired bird does not automatically need the calcium level of a layer ration.
Young-bird feeds often contain calcium around 1%, while layer feeds commonly contain around 3.5-4.5% or a programme-specific amount. Amino acids, energy and daily intake matter alongside these percentages.
