Barrier Poultry Calcium & D3 Boost

Important minerals include calcium, phosphorus and salt in a proper ratio, for the formation and maintenance of the skeletal structures of the body. Calcium deficiency can rise in warmer weather and is used less efficiently in older hens and so requirements rise as she gets older. Symptoms in a laying hen can be seen as thin-shelled eggs and even shell-less eggs. If the calcium requirement is not met to help form eggshells, she will steal it from her own bones. Aids bone development, egg shell formation and quality, blood clotting and heart function. Don’t offer before you have seen the first egg. No egg withdrawal period. Can be given direct or added to drinking water.
