Dried larva treat
The USA Grown Black Soldier Fly Larvae have become one of my flockâs absolute favorite treats! These 100% natural, high-protein grubs are a fantastic supplement for laying hens, ducks, and even reptiles. The quality is impressive â clean, evenly dried, and packed with nutrients that support strong eggs, glossy feathers, and overall vitality.I love that theyâre USA-grown and sustainably sourced, offering a healthier alternative to imported mealworms. With 85X more calcium and protein, they make a perfect boost for hens during molting or egg-laying seasons. The birds go crazy as soon as they see the bag come out!

The chickens accepted it very well
The truth is that I was surprised by this product, it is very well made and you can see the quality. My chickens accepted it without problem from the first day and they enjoy it a lot. I have noticed that they look more active, with brighter feathers and firmer eggshells, which gives me confidence that it is really providing them with good protein and calcium. I like it to be 100% natural, without additives or rare chemicals, that gives me peace of mind that I am giving something healthy. In addition, it brings good size of larvae and does not have a bad smell like other similar products. I definitely recommend it if you want to pamper your birds with something nutritious and quality.

Excellent Protein Treat for Happy Hens!
My chickens absolutely love these fly larvae! As soon as they hear the bag shake, they come running. Itâs a great source of protein, especially during molting season, and Iâve noticed healthier feathers and better egg production since adding them to their diet. The larvae are clean, not too dusty, and have a nice, natural smell (not overpowering like some brands). I also appreciate that theyâre sustainably produced â a nice bonus!Highly recommend for anyone who wants to give their flock a nutritious and exciting treat. Happy hens = happy eggs! ðð¥

The best protein for my birds!
The quality is outstanding, the percentage of protein is very good. The durability surprised me; you can tell it’s well done. My birds (Bird love) are delighted, they eat it well. The value for money is unbeatable. In just 3 days the percentage of posture has improved, and for me that is a very good indicator.
