Question 1

How long do green iguana eggs take to hatch?

Accepted Answer

Green iguana eggs take approximately 105 days to hatch on average, with a normal range of 90–120 days at a stable incubation temperature of 85–88°F.

Question 2

How do I calculate my iguana's hatch date?

Accepted Answer

Add 105 days to the lay date. Use the calculator above for an exact expected hatch date and the full 90–120 day normal range.

Question 3

What are green iguana nesting requirements?

Accepted Answer

Gravid females need a deep dig site — in the wild they excavate tunnels several feet long and up to 2–3 feet deep in sandy or loose soil, often communally. In captivity, provide a nest box at least 24 inches deep with a sand/soil mix moist enough to hold a tunnel shape without collapsing.

Question 4

What are the signs of egg binding in a green iguana?

Accepted Answer

A gravid female that stops digging or searching for a nest site for an extended period, along with straining, lethargy, and loss of appetite, can indicate egg binding (dystocia) — a veterinary emergency. Without an adequate nesting site, captive females are at meaningfully higher risk of becoming egg-bound.

Question 5

How many eggs does a green iguana lay?

Accepted Answer

A green iguana clutch typically contains 25 to 45 eggs, among the largest clutch sizes of any commonly kept reptile.

Question 6

How do I care for a green iguana hatchling?

Accepted Answer

House hatchlings in a humid enclosure with a basking spot around 95°F and UVB lighting. Green iguanas are herbivores from hatching — offer finely chopped dark leafy greens, vegetables, and a calcium supplement; avoid feeding insects or animal protein.

Question 7

What does a green iguana hatchling eat?

Accepted Answer

Unlike many reptiles, green iguanas are strict herbivores at every life stage, including from hatching. Offer finely chopped collard greens, mustard greens, squash, and other calcium-rich vegetables dusted with a reptile calcium supplement.

Question 8

How does iguana incubation compare to other reptiles?

Accepted Answer

At 105 days average, green iguanas incubate slower than bearded dragons (65 days) and crested geckos (90 days), but faster than monitor lizards (165 days) and most chameleon species.

Species	Avg. Days	Vs. Green Iguana
Monitor Lizard	165 days	60 days longer
Green Iguana	105 days	—
Crested Gecko	90 days	15 days shorter
Bearded Dragon	65 days	40 days shorter
