Helpful answers

Everything you need to know about feeding, delivery and caring for your hens.

Calci Worms

What are calci worms?

Calci worms are the larvae of the black soldier fly — a naturally occurring insect that is highly efficient at converting nutrients into a rich, digestible feed source. They are naturally high in calcium, protein and beneficial fats, making them an excellent supplement to your hens’ diet. Unlike processed feeds, calci worms are a whole, natural food that supports both nutrition and natural foraging behaviour.

What are the benefits for my hens?

They are naturally high in calcium to support strong eggshells, and they encourage natural foraging behaviour, keeping hens active and happy.

Are calci worms better than mealworms?

Calci worms naturally contain significantly more calcium than mealworms, making them a better choice for supporting eggshell quality. They also provide a more balanced nutritional profile for regular feeding.

Feeding & Care

How much should I feed my hens?

Feed approximately 10g per hen, per day. Our pack sizes are designed to make this simple based on your flock size.

How long does a pack last?

A 70g pack lasts one hen for one week. Larger packs scale depending on how many hens you have.

How should I store them?

Keep them in a cool place, ideally in the fridge. This slows their development and keeps them fresh for longer. Do not freeze.

Are they safe to feed every day?

Yes, when fed at the recommended amount (around 10g per hen per day), they are a safe and healthy daily treat.

What if my hens don’t eat them?

It’s very rare, but hens can take a day or two to get used to a new treat. Once they try them, they usually love them. If they still don't like them, we'll give you a full refund.

What is SuperFrass?

How do I use SuperFrass?
