Why Calci Worms Are a Must‑Have Superfood for Chickens

If you keep chickens, you already know that feeding them isn’t just about filling a feeder. Most people who care for hens want to do the right thing — to give them food that supports their health, keeps them laying well, and reflects the care they put into their flock every day. That’s why more and more chicken keepers across the UK are turning to live Calci Worms as a natural, nutritious treat.

At Syntects, we speak to chicken owners every day, from first-time keepers to experienced smallholders. One thing they all have in common is the same question: “What can I give my chickens that’s genuinely good for them?” Calci Worms are often the answer.

Chickens are natural insect eaters. Long before pellets and layers mash existed, hens spent their days scratching, pecking, and hunting for bugs. When you offer live Calci Worms, you’re not introducing something artificial or unnecessary — you’re tapping into instincts that chickens have always had. The difference is that Calci Worms deliver that natural behaviour alongside exceptional nutrition.

What makes Calci Worms stand out is their balance of protein and calcium. Protein supports feather condition, muscle strength, and recovery during moulting, while calcium plays a vital role in eggshell quality and bone health. Many keepers notice stronger shells and more consistent laying once Calci Worms are introduced as a regular treat. It’s not magic — it’s simply giving hens nutrients in a form their bodies are designed to use.

There’s also something important to be said about how Calci Worms are fed. Because they’re live, chickens don’t just eat them — they chase them, scratch for them, and get visibly excited when they appear. That activity matters. It keeps birds mentally stimulated, encourages movement, and helps reduce boredom, especially for flocks that spend time in enclosed runs. Watching a group of hens go mad for Calci Worms is often enough to convince people they’ve made the right choice.

Of course, not all Calci Worms are equal. Freshness, quality control, and responsible production matter — not just for compliance, but for your chickens’ wellbeing. Syntects produces live Calci Worms here in the UK, with a strong focus on freshness and care at every stage. That means what arrives with you is lively, nutritious, and ready to feed, not something that’s been sitting around losing value.

For most backyard flocks, Calci Worms are best used as a treat rather than a replacement for a balanced diet. A small handful offered a few times a week is enough to make a difference, whether you’re supporting laying hens, helping birds through a moult, or simply rewarding your flock. Many keepers like to hand-feed them, while others scatter them to encourage foraging — both approaches work, and both strengthen the bond between you and your birds.

If you’re feeding a small flock and want an easy way to introduce Calci Worms, Syntects offers live Calci Worms in convenient 100-count packs (25g), ideal for regular treating and trying them for the first time. For larger flocks or keepers who already know how much their chickens love them, the bulk option of 1kg supplied as two 500g bags offers better value while maintaining the same freshness and quality standards.

Beyond the nutrition, what matters most to many chicken keepers is peace of mind. Knowing that what you’re feeding is legal, responsibly produced, and supplied by people who genuinely understand chickens makes all the difference. At Syntects, education and support go hand in hand with our products — because healthy chickens start with informed keepers.

Calci Worms aren’t a gimmick or a trend. They’re a simple, natural way to support your flock’s health while giving them something they instinctively love. If you’re looking for a treat that aligns with how chickens are meant to eat, and a supplier you can trust, live Calci Worms from Syntects are a natural place to start.
