Order ECOnourish’s LIVE Black Soldier Fly Larvae (aka Calci Worms for Chickens)

What do you want for your flock? Immune support to protect them from disease? Support during moulting? Help with egg-production issues? Putting an end to inappropriate pecking behaviours? Lustrous feathers and boundless energy? A new way to enrich their lives? All of the above? Our LIVE Black Soldier Fly Larvae, or Calci Worms are the answer to your poultry prayers!

Here’s why:

  • Enrichment: Happier, healthier, busier hens!
  • Gut Health & Immunity: Pre and probiotics, a special fibre called chitin and essential fatty acids improve digestion, reduce gut inflammation and improve their gut microbiota for gut health and immunity.
  • Disease Prevention: Anti-microbial peptides fight bacteria and parasites while powerful anti-viral lauric acid fights common viral diseases – even Avian Influenza.
  • Protein Power & Calcium Kick: Improve plumage and support egg production, bone and beak health when they need it most – like during moulting and intense laying.
  • The Balancing Act: Calci Worms’ Calcium: Phosphorus ratio makes it a unique, natural food that achieves the perfect balance for hens.

But wait, there’s more!

  • Stress Relief: Scientific studies demonstrate reduced hen stress with our Calci Worms. It’s a chill pill for your flock!
  • Social Smarts: Promote harmony amongst your flock by giving them a shared pursuit – something to chatter about. Helps with bonding, integrating new birds and social challenges.
  • Eco-smart: Sustainably reared, our Calci Worms turn you and your flock into garden eco-warriors.

It’s more than a chicken nutrition supplement. This is about delight, enrichment and vitality. It’s the joy of your hens foraging, racing for these nutrient-filled morsels. They’ll run and fly to you when you get out the tube – and they’ll follow you anywhere for them! Very handy for training them to get back into the run. It’s about the satisfaction you feel knowing you’re providing the best while caring for our planet.

So embrace the ECOnourish difference and treat your hens with LIVE Black Soldier Fly Larvae – the holistic health supplement your chickens will peck your hand off for (hopefully not literally).

Larvae Care

Remove the seal when they arrive, even if you aren’t feeding immediately,

Store the container upright and in warm conditions – not outdoors in cold weather.

Larvae become inactive when cold but if they’re still they are not dead.

If your larvae get cold, take off the lid and store in warm conditions, they will perk up after 30-60mins.

    They now love the wrigglers as I call them but first couple of days most of them were suspicious. The video will show several days and how they have grown to love them. Winnie comes running out of her moulting hidey hole to get them! Winnie comes running out of her moulting hidey hole to get them. Brilliant product

    I thought I would give these a go to see what they would make of the live worms. At first they didn’t know what to make of them but has you can see from the videos they soon loved them! Audrey is such a greedy pig and always tries to make herself bigger to stop the others from getting at the treats! Will definitely be buying these again especially if they have to go back in the barn this winter due to flockdown.

    I would definitely recommend the live larvae to other domestic owners of ex-battery hens. I feel it has definitely contributed to their mental and physical recovery and restoration to natural condition.

    We’ve been using it a month and the hens are shinier than they were, leap around with even more than normal enthusiasm when being fed and genuinely seem to be feeling more energetic.

    This is day 2 of the bugs and the chickens are absolutely CRAzY for them!!! It’s amazing! I’m going to start free ranging them in a small area of the garden and these will be a very handy lure to get them back in their run.

    Our hens from @thecoveychickinn absolutely adore the live larvae! Not only are they filled with protein & calcium, they even help improve feather coverage which for our molting girls is ideal. We absolutely love this new small business and their entire ethos around being environmentally friendly so we will definitely be regular, returning customers. The delivery was super speedy as well as the product being reasonably priced. Happy hens all round!

    My three hens absolutely loves this and they get so excited when they see the box in my hand. I have stopped buying other treats as there is no waste with the live larvae

    Discovering ECOnourish and its Calci Worms has been so beneficial to my small flock. My white Sussex, Daisy was quite poorly when I placed my first order in June. Her transformation was truly remarkable. Her feathers grew back, her appetite improved but most importantly, she became a happy hen again. Although her tumour was terminal, she spent her last 4 months enjoying life.

    Having seen just how much benefit all my hens gain from your Calci Worms, I wholeheartedly recommend them. Making use of the subscription service is so easy and ensures I don’t run out of them; they are a must-have for my chooks. I have to mention that even on her last morning Daisy came out for her Calci Worm breakfast! You couldn’t get a better recommendation than that?!?

    I needed to share how impressed I am with @econourish.superfood black soldier fly larvae for hens. I discovered them through @mad4hens post about them. All my chickens love them, but where they’ve really made the difference is in inspiring poorly Selene to eat again! Selene is an ex caged bird. She suffered something sudden and neurological a few weeks back and I found her unable to use her legs and unable to see anything. She showed me a will to live though. On a course of steroids, she is gradually recovering the use of her legs and I believe she can now see from her left eye but not her right. She drinks by herself but despite being hugely enthusiastic about receiving syringe feeds, was not interested in feeding herself. Until I sprinkled black soldier fly larvae onto her mash – then all of a sudden there was no stopping her! Her depth perception is wonky and there’s a lot of stabbing to find them, but honestly this product has saved her life as I don’t have time to keep hand feeding twice a day forever so I was facing a difficult decision. Now she has another chance at life as I can be confident that she will eat something even when I’m not there. Hurrah!
