Eggs can be very nutritious for bearded dragons; they contain a decent amount of protein, vitamins, and essential minerals. Very rich in assorted vitamins such as vitamin A, B, C, D, E, and K, and minerals such as zinc, folate, calcium, selenium, magnesium, and more. However, with them being so rich in these elements, it can be easy to overdo it, which is why when you offer eggs to your pet dragon, it should be sparingly. Too much protein in a dragon's diet can lead to health problems such as gout, and this is why eggs are best used as an occasional treat or for a dragon that may be suffering from malnutrition. Eggs are also useful for when you cannot find live feeders and need an emergency protein replacement.
Live feeders should always be used as the dragon's primary protein source; alternatives such as eggs are only to be used under certain circumstances.
Quail eggs can be useful if you can find them since they are small so easily offered and the dragon can even have a whole egg, if giving them a chicken egg then you should only provide them half an egg at a time. Eggs should always be organic and free-range.
To prepare eggs for your dragon, you can make boiled eggs or scrambled eggs, whichever you find easier. Some dragons may prefer one or the other. It doesn't matter which one you make, but you mustn't use any ingredients other than just the egg. No oil, which will make your dragon have awful diarrhea, no butter, milk, or any dairy products as dragons are lactose intolerant.
