- KRKim R.Verified BuyerReviewingGrubbliesI recommend this productRated 5 out of 5 stars7/8/25They come runnin'!
I have 14 chickens that come runnin' when I have a bag of Grubblies in my hand. My two leghorn hens are ALWAYS first in line and will jump up on a stump to make sure I see them when I'm holding the bag.
But fun stuff aside, I also can shake this bag if I see/hear hawks or eagles in the area and everyone races back to the coop. I love that I can choose the Hometown blend!
Grubbly Farms7/8/25We love this so much! Your leghorns sound like true Grubblies superfans. It's amazing how something so fun can also be such a helpful tool for keeping your flock safe. We're so glad you're enjoying the Hometown Harvest and grateful to be part of your daily routine with your girls. 💚

My chickens literally scream when they see they are getting grubblies. Quality is outstanding. Worms are fully formed and they are not broken or the bag half dust like other brands. Will be a staple for my flock!

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.
