Do hens need multivitamins?
A complete ration appropriate to life stage should provide the nutritional foundation. Extra supplements are not automatically needed, and excessive amounts of some nutrients can be harmful. Discuss a specific concern with a poultry-experienced veterinarian.
Feather moulting
Moulting birds need appropriate nutrition and gentle handling. Do not replace balanced feed with treats or assume that a proprietary tonic will speed recovery. Severe feather loss, damaged skin or illness needs investigation.
Calcium and vitamin D
These nutrients matter for skeletal health and laying, but weak shells and weakness have several possible causes. A vet can assess the diet and decide whether supplementation or another treatment is needed. Avoid guessing doses.
Broodiness and recovery
Monitor whether a broody or recovering hen eats and drinks normally. Reduced intake or loss of condition needs attention. Vitamins cannot substitute for suitable care, diagnosis or treatment of the underlying problem.
Parasites and product claims
Supplements do not clear a confirmed mite or worm infestation. Choose treatment with veterinary advice and check suitability for laying hens and withholding directions. Do not combine multiple products simply because they are described as natural.
