Small eggs: what to record before changing the diet
Egg size varies with breed, age, stage of lay and individual bird. A small egg is not automatically proof of low protein. Measure a pattern before changing several parts of the diet.
Use consistent measurements
Weigh eggs with a suitable scale and record the pen, date and whether the birds recently moved or began laying. Note shell quality separately from weight. Reject cracked or unsuitable eggs from hatching stock according to your selection policy.
Check intake and balance
Look at the complete feed label, how much the flock actually uses and whether birds select grains while leaving other ingredients. Protein percentage alone cannot describe energy, amino acids or mineral intake. A scoop of supplement may change the balance in ways that are difficult to predict.
Check the birds
Body condition, age, stress, health and water availability all matter. Persistent changes associated with poor condition or other abnormal signs need professional assessment. Do not promise that adding herbs will produce a specific egg weight.
Next step: collect two to four weeks of records if the birds remain well, and seek advice sooner for illness. Compare meaningful averages rather than the largest egg from one hen with the smallest from another.
