    They come running!

    The flock at HeartSong Ranch knows when it's Grubblies time! They come running to the fence as we get closer - and crowd the gate when we come in (no photos because our hands are full).

    The local feed mill gave us some free sample - the chickens tried it and left it mostly uneaten. Their "grubs" looked emaciated and empty. Grubblies look well fed and nutritious and that's what the flock picked.

    We’re so glad to hear your flock is eggcited for Grubblies and that they recognize the difference in quality. It’s wonderful to know snack time is always a hit at HeartSong Ranch! 💚

    Our Hens ❤️ Grubblies

    When the girls hear me shaking the tub of Grubblies, they start running my way clucking with joy. They just can’t get enough of them! And the added protein makes for better eggs and more of them. Happy hens - happy humans. It’s a win win for everyone ❤️

    Crazy for Grubblies

    My chickens are loving their Grubblies. They can’t wait to see me every morning and run to their feeder. Their eggs are beautiful- large, strong shells, and sometimes double yolks! I’ve experienced wonderful customer service and deliveries are right on schedule.

  • 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.
