Lifecycle Milestones for Bearded Dragons

Hatchling Stage

The hatchling stage of bearded dragons starts from birth and lasts for a few months. During this time, they experience rapid growth and are extremely active. Hatchlings are small in size, typically measuring 3 to 4 inches in length.

As they grow, shedding occurs more frequently to accommodate their expanding bodies. It’s essential for hatchlings to have a nutritious diet, mainly consisting of small insects like crickets and finely chopped vegetables, to support their growth and development.

Juvenile Stage

The juvenile stage begins when the bearded dragons measure around 8 inches in length and lasts until they reach 12 to 18 months of age. This stage is characterized by fast-paced growth and a voracious appetite. Juveniles can consume up to 50 crickets every day and require a constant supply of fresh vegetables.

During this phase, shedding continues to occur regularly, and their bodies develop further. By the end of the juvenile stage, bearded dragons will grow to about 15 to 18 inches in length, and their weight may range between 300 and 550 grams.

Adult Stage

Adult bearded dragons have reached sexual maturity and their maximum size, which usually happens between 12 and 18 months of age. Fully grown bearded dragons measure anywhere from 16 to 24 inches in length, with their tails often being as long, if not longer, than their bodies. Their weight typically ranges from 380 to 510 grams.

During the adult stage, growth slows down significantly, and shedding occurs less frequently. Brumation, a period of dormancy similar to hibernation for cold-blooded species, is observed in adult bearded dragons. While they still require a balanced diet, the proportion of insects to vegetables should be adjusted to maintain optimal health.

It’s important to closely monitor the health and well-being of bearded dragons throughout their life stages, ensuring proper nutrition, temperature, and humidity within their enclosure. By doing so, you will help them thrive and reach their full potential in size and lifespan.
