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.

    I have run out!! And the girls are angry with me!! They love them and are shiny and healthier looking than at the start… I think you have a great product.

    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.

    The ladies loved their first taste of live soldier fly larvae! They’re obsessed! Thank you @econourish.superfood.

    What a great product!

    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

    A great, natural, British, small business that supports a fabulous eco friendly ethos plus our chickens go wild for the products! Low cost with really speedy delivery too. It’s a win win all round

    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!

    My Hens LOVE them!
    I am so glad I found ECOnourish for my hens. They absolutely love them for their breakfast. It’s a great way to get nutrition and vital vitamins into them. I have set up a subscription so my girls don’t run out – breakfast time would be painful without ECOnourish!!! (That is painful for me)

    Such a wonderful product, I have even got my picky Silkies to enjoy their daily boost of protein! They are thriving and have come through their moult well.
    I have a weekly subscription delivered easily and promptly by my postman!
    Thankyou ECOnourish.

    Happy Hens happy me
    I bought these black fly soldier larvae after my hens went through a heavy moult and at 25 weeks they still weren’t laying despite being winter layers. After just 2 weeks on them my cream legbar started laying on 2nd January. My Faverolles combs have now gone very red and Speckled Sussex also. They now wait at the door end of the run for me every day at 1 pm I can barely get in the run for their excitement! It fills my heart to see such enjoyment and nutrition for my girls. Looking forward to see how these help the two rescue hens from BHWT I will collect this weekend.

    Quick delivery. Easy to navigate booking system and the container arrived intact. The BSF larvae look healthy and the hens are very happy!

    My girls love them! Always great service.

    My bantams love these yummy, wriggly, fresh grubs. I have run out and they are not impressed!

    Caviar for chickens well worth it
    This is a wonderful treat to feed your hens with as if done daily their health positively glows. Eco nourish has resulted in my birds moulting faster, growing shiny, new feathers and blossoming red combs they look a picture of health despite the winter wet and cold, I’m sure Eco nourish is the factor behind this as my hens are elderly birds. It’s great to know this a sustainable product and the packaging is all recyclable. My hens act like this is caviar and wait for their supper of it each afternoon, well worth it.

    The answer I have been looking for!
    I have been looking to source an eco friendly but also budget friendly live food for my Rankin’s dragons.
    I was spending more money for about 1/10th the amount of worms from another supplier. The worms were tiny. The ones from Eco Nourish are huge and juicy and you get so much for your money. The container is also recyclable but is also much nicer to have around instead of clear plastic containers that you can see into.
    Excellent, I am very pleased with my subscription.

    Initially my birds were really suspicious and didn’t want to touch their new snack but decided to give them a try and now they love them. The birds are full of energy and really lovely plumage and general condition. It must be down to the larvaes. Shipping was excellent, really quick and the larvaes were all alive when they arrived.

    Prompt reliable delivery. Good product which my hens love. They ambush me at 3pm for their daily snacks!
