Why chicken keepers choose Calci Worms
✔ Natural nutrition chickens love
Live Calci Worms are naturally rich in calcium and protein, making them a popular supplemental treat for chickens when fed alongside a complete feed.
✔ Encourages natural behaviour
Because they’re live and moving, Calci Worms trigger instinctive pecking, scratching and foraging, helping keep chickens active, occupied and mentally stimulated.
✔ Ideal for everyday flock routines
The tube format allows you to portion exactly what you need — a small handful or a larger feed — without waste or mess.
✔ Suitable for all types of chickens
Commonly fed to:
-
Laying hens
-
Bantams
-
Pullets and growers
-
Broilers
-
Rescue and ex-battery hens
-
Mixed backyard flocks
When chicken keepers often use Calci Worms
Many keepers add Live Calci Worms during:
-
Moulting (as a treat alongside normal feed)
-
Winter months, when natural insects are scarce
-
After stress, such as rehoming or changes in the flock
-
Training & taming, as a high-value treat birds respond to quickly
Why live matters (UK feeding note)
In the UK, live insects are commonly chosen by chicken keepers as a practical and permitted way to provide insect-based enrichment and treats, rather than processed insect products.
This is why our Calci Worms are supplied live, fresh, and ready to feed.
