Dr. Rob Marshall's Hi-CAL

Hi-CAL is a potent source of calcium that is readily absorbed. It is added to the drinking water or dosed via crop tube. Hi-Cal is used to prevent soft-shelled eggs and to help prevent egg-binding and other related problems. Hi-Cal contains NO Vitamin D3 or Magnesium (essentials required for proper calcium absorption). It should always be used with a full spectrum vitamin supplement containing Vitamin D3 & Magnesium, or may be used as a stand-alone product when aiding an egg-bound hen. This product should NOT be used as a stand alone calcium supplement without proper Vitamin D3 & Magnesium support. Hi-Cal should be used when egg-shell problems are the result of moulding disease or bowel infections (e.g. E.coli diarrhea, sweating disease). These diseases prevent the proper absorption of minerals even though they are provided to the breeding birds. For individual birds with a history of egg-binding, Hi-Cal should be added to the drinking water a few days after the pair is placed in the breeding cage and continued until the clutch is complete.

When used as a regular calcium supplement, Hi-CAL should be combined with Dr. Marshall's Inca Honey which does contain Vitamin D3.

Dosing Rates:

Dose Hi-CAL directly by mouth (use a crop needle or syringe) for egg binding, egg laying paralysis, and sick breeding hens. Administer in drinking water or via soft food for egg shell problems (soft, rough, or malformed eggs).
