Shipping Frequently Asked Questions

All orders are shipped and dispatched from our facility in Mount Barker, SA. Orders with items displayed as ‘in stock’ on our site are processed and shipped next day. With the Exclusion of weekends and public holidays.

We can only ship Small Accessories to PO Boxes, while larger items like Next Boxes and other accessories must be shipped to residential or commercial addresses due to their size. Unfortunately, we’re unable to accommodate custom delivery requests such as scheduling specific delivery dates and times, leaving the package in a particular location, or calling in advance or on arrival. These requests can only be accommodated if a customer organises freight collection and services themselves.

The packaging should ensure that the product arrives in brand-new, perfect condition. Nestyboxes takes great care to ensure that the product is dispatched from our facility in perfect condition. Even though we hope it won't, if an item is harmed in transit or a portion of your delivery is missing, kindly let us know as soon as you can after receiving your order by contacting us using the information on our Contact page.

When placing an order, you have the choice to select "authority to leave" during the checkout process (ATL). In this case, without a signature being required, our shipping carriers will leave the delivery at your unattended location. It's important to understand that this delivery method carries no guarantee against loss or damage, and neither NestyBoxes nor the shipping companies we work with cannot be held responsible for it.
It might not always be possible for the shipping carrier to leave a package with ATL instructions, though. This might happen, for example, if the delivery address is inside a secure building or complex and appropriate access to the address is not possible, or if there are insufficient instructions regarding where to leave the delivery.

All your questions answered

So long as you provide the shell grit blocks one at a time, out of the weather where poultry have free access to it, you should not have any issues with overdosing on shellgrit. Chickens are able to regulate their own intake and will freely choose to supplement themselves with calcium when the need to. However, if you do notice soft egg shells or identify a calcium deficiency, we advise temporary use of Nesty Calci-Boost to fix these severe deficiencies.

Both loose and pressed blocks of shellgrit are an excellent way to supplement poultry with additional calcium. There is no right or wrong choice with what form to use. Providing your flock with a shellgrit block however, will help minimise your flock wasting shellgrit by kicking it out. Unlike loose shellgrit, blocks don't need to be stored in a bowl either.

It is not advised to feed two calcium sources at the same time as it may result in an overdose. Feed Nesty Calci-Boost when a known calcium deficiency is present and provide shellgrit blocks as a top up in between.

The Nesty Shellgrit blocks are made from limestone that is then formed into the shape of shells. It is highly soluble and an excellent source of calcium. Nesty uses their in house designed, all-natural and non- toxic glue formulation to set the Shellgrit blocks to perfection. The gluing agent does contain a small percentage of gelatine (a product derived from animals), therefore making it not vegetarian only. Chickens are however, an omnivorous species and will benefit from eating meats and meat by-products as it is a quality source of protein and valuable nutrients.

If your Shellgrit gets soiled, dispose of it and replace with fresh shellgrit.

Yes, shellgrit is a safe and soluble source of calcium that can be provided to all poultry. Poultry with beaks will find consuming the Nesty Shellgrit Block easier than poultry with beaks, Nesty advises to address this accordingly.

Supplementing shellgrit in your flocks diet will aid in bone and skeletal formation, strong eggshells, and quality egg production.
