- CCChristian C.Verified BuyerReviewingGrubbliesI recommend this productRated 5 out of 5 stars8/19/26Amazing Quality Product!
I couldn't believe how hard it was to find black soldier flies sourced from the United States/Canada. All the products in stores were sourced from China which I wasn't too confident in their farming practices and microwave dehydrating methods. I'm grateful to find Grubbly Farms, my hens run towards me at feeding time and peck straight from my hand! The freshness and color difference in quality is above all others I've used. Thank you Grumbly Farms Team!!

FAQ

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.
-
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. Unlike some farms that can sometimes feed grubs a host of questionable food sources, our grubs consume only pre-consumer fruits, veggies, and grains, ensuring nothing harmful passes through to your pet except clean protein and top-notch nutrition.

While we’re committed to a natural approach for naturally healthy chickens, currently, there are no black soldier fly grub farms that grow organic grubs. Grubblies are grown on fruits, veggies, and grains from farms, restaurants, and grocery stores that would normally go to waste. These pre-consumer products are non-organic, therefore, our grubs cannot be considered organic. However, you can rest assured they are fed a healthy, balanced diet that never includes post-consumer waste or farm manure.
Grubblies are all-natural, free of GMOs! However, we do not hold a Non-GMO certification from the Non-GMO Project.

Yes! Grubblies are a fantastic snack for all types of birds and many other animals. Mixed flock owners often comment on how much all of their feathered friends love Grubblies.
-
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.
-
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.
