Why Give GrubTerra to your flock?
Weak eggshells are a common issue for many flock owners, leading to cracked or broken eggs that are difficult to collect and costly to lose. Without enough calcium and proper nutrition, your hens’ eggshells can become thin and fragile, making them prone to breaking and reducing the quality of each egg. Fragile shells not only waste eggs but also affect your hens’ overall health and egg-laying consistency.
GrubTerra Black Soldier Fly Larvae offer a nutrient-rich solution with the calcium, protein, and healthy fats your hens need for stronger, more resilient eggshells. By incorporating our larvae into their diet, you’re giving your flock the essential nutrition they need to lay crack-resistant eggs, ensuring a healthier, more productive flock.
5 Reasons Why GrubTerra Grubs Can Help Strengthen Egg Shells!

TRUSTED BY CHICKEN AND BIRD-OWNERS, LOVED BY POULTRY!
I've been feeding my hens GrubTerra's black soldier fly larvae for a few months now and have seen amazing results! I have 9 hens, and before we started using GrubTerra, we were getting at least 1 soft egg per week. After feeding our hens GrubTerra we have never had that problem again!

Here’s How We Compare
Grubterra stands out from the crowd, because we care about the details.
My chickens love Hen Harmony! I love being able to give my flock something extra as part of their routine. It’s always nice finding products that make caring for my girls a little easier. Definitely happy to have this in our flock’s lineup! 🐔❤
The chickens don't even notice that anything has been added to the food - but over time, you can definitely see the difference. Firmer egg shells and more vibrant coloring on the combs are probably the two most obvious. Highly recommend Peck Purity!
I have a flock of pullets, hens, roosters, chicks, and turkeys. I absolutely adore my chickens and care about their health. I truly believe in prevention in the most natural way possible. My birds loved when I added Peck Purity to their feed. It smelt so good the turkey tore the bag out of my hand as I added it! I had to take a double take and smell it again myself. It was easy for me to add to their feed and knowing I am helping aid in gut health (the powerhouse of everything!), I feel great giving it to them!
At The Fluffed Crown Homestead, we're always looking for products that help support the health and well-being of our flock while keeping things simple for busy chicken keepers.
One thing I immediately liked about Hen Harmony was how easy it is to use. The included scoop makes measuring simple, and adding it to the flock's water takes only seconds. I also appreciate that it's made in the USA and contains natural ingredients, which is something that's important to me when choosing products for my birds.
With seasonal weather changes approaching, I wanted to add extra vitamins, minerals, probiotics, and electrolytes to help support my flock, and Hen Harmony provides all of that in one product instead of having to purchase several separate supplements.
So far, the chickens have had no issues drinking it, which is always a win when introducing something new. I'm excited to continue using it and monitoring the flock over time.
Thank you, GrubTerra, for the opportunity to partner with The Fluffed Crown Homestead and allow us to share our honest experience with our community of backyard chicken keepers and homesteaders.

Everyday the ducks a the chickens line up for their treats. As soon as they hear the sliding door open they rush over as fast as their little legs will waddle
I've got 30 chickens so I make 2 treat pans for them with Peck Purity on top and they can't get enough. Their poops are firm and their vents are almost sparkly clean! I give that credit to Peck Purity, love this product! Thank you, my girls love it and I'll never stop buying it.
I highly recommend GrubTerra and their Hen Harmony supplement. After using it with my flock for the past couple of weeks, I’ve noticed a clear improvement in overall egg production—roughly a 25–30% increase for my hens.
The chickens enjoy it, it’s easy to add to their normal feeding routine, and I’ve been very happy with the results. Based on my experience so far, Hen Harmony has definitely earned a place in our regular flock-care routine at TE&A Hatchery.
I would absolutely recommend GrubTerra to other backyard chicken keepers and poultry owners looking for a quality supplement for their flock.
I give this to my 5 girls every night before bedtime to give them a calcium boost. When they hear the can lid open they know it's time for treats and come running!
My chickens were having watery poops who knows what they got into being free range. I must of talked about it because I started seeing your adds on social media and thought why not give this a try.

I definitely would give this product a try if you think your girls are having gut issues
