    Love Grubblies

    I have been ordering grubblies for years now and love their product. I love the quality and they are USA. The shipping is fast and the customer service is great. It is hard to find good customer service nowadays. I feed them to my wild bluebirds and they love them. They are much better than mealworms, which are calcium depleting. They are expensive but worth it.

    Thank you so much for your continued support and kind words! We’re thrilled to hear your wild bluebirds are enjoying Grubblies as much as your chickens. We’re always here to provide the best quality and service for you and your feathered friends. Thanks for being part of our 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.
