Liquid calcium and vitamin D3 supplement for birds and small animals. It is a palatable syrup that can be diluted in drinking water or administered directly to the bird. Calcivet can be used in egg bound birds to aid in expulsion of the egg and in cases of soft shell eggs, to deliver calcium. Calcivet should be administered to breeding birds for approximately one month prior to egg laying and through the chick rearing period. Calcivet & Vitamin D3 Liquid 250 ml/cc (8 oz)
