Frequently Asked Questions
Everything you need to know about switching your flock to Grubblies.
How do Grubblies compare to other snacks for chickens?
Grubblies help fuel our pets and the planet. Every peck of sustainably harvested grubs is loaded with nutrients for our fluffy ones. Grubblies are rich in protein for strong, healthy feathers, and contain over 50x more calcium than mealworms for stronger eggshells. Grubblies are also completely natural, which means they are not genetically modified, nor is anything added. Just shake the bag and watch them come running for a healthy snack they love.
Where do you source Grubblies from?
Grubblies are harvested on grub farms in the USA & Canada. All of our grubs are raised in strict adherence to EU standards, the highest grub standards in the world.

Do Grubblies count as a chicken protein and calcium supplement?
Many flock owners feed their feathered friends Grubblies as a tasty, fun, healthy way to supplement their girls’ calcium and protein. In fact, grubs have a 34% protein level. They’re also rich in calcium with 50x more calcium than mealworms.
This comes in handy throughout the year, but especially during and after molting season and in winter when chickens benefit from more protein.
What is the serving size for Grubblies?
Serve up to ¼ cup per adult bird as a daily snack. When molting, supplement your feed with a double serving of protein-packed Grubblies. For chicks, give 1-2 pinches daily - just like they would get in nature. Serve with chick grit and access to fresh water. Introduce new foods gradually and give your flock access to grit to aid digestion.
