How to treat calcium deficiency in birds

Calcium is one of the most important vitamins for birds, and especially for laying hens. Calcium deficiencies are most apparent through bone growth and reproductive health. In pigeons and parrots, symptoms of a calcium deficiency include egg binding, soft-shelled or brittle eggs, small clutches, poor quality crop milk, lameness, osteoporosis and skeletal deformity. In hatchlings, deficiencies may present as poor growth, rickets, deformities and poor hatch rates. For the symptoms of calcium deficiency in chickens, including laying hens.

However, treating the symptoms of a calcium deficiency is not as simple as adding more calcium to the bird’s ration for two reasons:

  1. The symptoms of a calcium deficiency are easily confused with those of a vitamin A deficiency. Both nutrients are commonly lacking in seed and pellet rations, meaning vitamin A deficiencies are common in caged birds.
  2. Vitamin D is vital for calcium absorption, so a lack of vitamin D can lead to a calcium deficiency even when sufficient calcium is available in the diet. In caged birds without access to ample direct sunlight, vitamin D deficiency is a frequent cause of calcium deficiency.

As it is hard to identify the true cause of the symptoms of a calcium deficiency without expensive medical tests, the best practice is to regularly supplement rations with a calcium source that is fortified with vitamins A and D3, in order to address all possible causes of ill-health.

D-3 Liquid Calcium is an easy-to-administer calcium source that also includes with vitamins A and D3. It is perfect for birds on seed-based diets, including laying hens.
