What Are Iguanas?

There are over 300 species of iguana worldwide. Iguanas come in many colors and sizes.

For their large size, iguanas are comfortable living in treetops. This arboreal creature will usually stay in the trees that are close to bodies of water such as rivers, ponds, and even oceans.

How To Prevent Iguanas From Killing Your Chickens

While it’s highly unlikely that an iguana will kill your chicken, it is still possible.

Iguana is very territorial and will attack everything that comes within range.

Also, the iguana is known to eat young and baby chickens, only if there are no other food sources around.

There are many ways to keep the iguanas out of the yard, far away from the chickens.

Below are some possible ways to keep the iguanas away:

Clean Up The Yard

Iguanas are always looking for an easy meal. This means garbage, leftover foods, or even fruits and vegetables that fallen from the garden. All of these will entice the iguanas to come into the yard.

Iguanas are known to return to the same area if their food is easily accessible to them.

Do Not Feed the Iguanas

If there are wild iguanas around, avoid feeding them anything, even just a small piece of food. If they know this is the place to get food easily, they’ll keep returning.

When they do return, and you’re not around, they will go after chicken eggs and even the smaller chickens if they see an opportunity.

Cover Warm Surfaces

Like many reptiles, iguanas are cold-blooded animals, which means they need the sun to regulate their body temperature.

To ensure they do not come close to your chicken, keep places like rocks, sidewalks, and logs covered.

Keep a Rooster

A rooster is a great way to keep the chickens safe. The main job of a rooster is to protect the flock from danger, even if it means costing their own life.

If an iguana comes within range, the rooster will crow loudly to alert the flock of danger. This will give the chickens enough time to run for cover.

If the iguana gets too close to the flock, the rooster will fight the lizard.

Install Sprinkler System

Install a sprinkler system around your entire yard to keep the iguanas away. You can install one that is motion-activated so every time an iguana comes within range, it will activate the sprinkler system. It will spray water on the iguana, which will scare them away.

Iguana Repellant

If you can seem to find any of the methods above that works, you can give Iguana Blocker- All Natural Repellant a try. It doesn’t kill or even hurt the iguanas. It is biodegradable and safe to use.

All you need to do is spray it around the chicken coop or around the entire yard. This will prevent the iguanas from coming into your yard. Once they smell the repellant, it will drive them away.

Iguanas are a popular pet to have. For that reason, most people will wonder if their pet iguana will eat chickens.

The simple answer is, YES! If an opportunity arises, the iguana will waste no time attacking and killing the chickens. However, they will only go after smaller chickens and their eggs.

Therefore, keep the iguana in their own area, so they have no way to get to the chickens.
