Can bearded dragons eat corn?
Only as a rare treat: not part of a regular diet.
Poor calcium to phosphorus ratio; a rare kernel treat only.
Also known as: sweetcorn, corn kernels.
How often can bearded dragons eat corn?
Rarely, and in small amounts. Treat it as a treat: something offered now and then, never a fixture of the diet. How much depends on the animal’s age and weight rather than a fixed spoonful, the feeding chapter sets portions by weight and covers the supplement cycle that goes with them.
What’s in corn for a bearded dragon?
Phosphorus outweighs calcium in corn (about 1 to 44.5), the wrong way round for the 2:1 balance a dragon’s blood has to hold. It also carries 6.3 g of sugar per 100 g. The supplements chapter explains why that balance matters.
