Agrivite Enhance Feather Shell 'n' Bone

Like most other animals (and humans) calcium is vital for the growth of strong healthy bones. However, in egg-laying fowl its needs are twofold. Calcium is the key ingredient for their bones and for good eggshells, along with vitamin D. Giving a calcium boost to poultry at times of stress, illness or during winter when daylight hours are short, is beneficial.
