Diatomaceous Earth for Chickens

Diatomaceous Earth for chickens is marvellous and I wouldn’t be without it in my poultry supplies. It has many uses for my birds but also other animals and bug control around the home. It consists of micro skeletons of fossilised remains of deceased diatoms, which are a type of algae found in both sea water and fresh water.

diatomDiatomaceous Earth has a wide variety of uses such as in filtration (drinking water filters, fish tanks and swimming pools), abrasives (it is in some toothpaste and facial scrubs), as an absorbent for liquids (like cat litter), and it is used in dynamite to make it more stable. Food grade diatomaceous earth is particularly useful to reduce internal and external parasites (such as Worms, Lice and Mites) in animals, including poultry.

How Diatomaceous Earth works

The powder absorbs lipids from the waxy outer layer of red mites and lice, which causes them to dehydrate and then die. For internal parasites, the abrasive microscopically sharp edges will kill many of the worms with regular use (it must be used daily for it to be effective) although remember there are also larvae in the bloodstream that won’t be killed by diatomaceous earth. It is for this reason, I personally believe using a chemical wormer two or three times per year (I use Flubenvet although this isn’t licensed for ducks in the UK even though I know many people who use it) to make sure.

Always remember to wear a dust mask when using dusting powders to avoid inhalation.

Good poultry suppliers will sell food grade diatomaceous earth in tubs that can be used in the following ways as an organic approach to parasite control. Do not be tempted to buy industrial diatomaceous earth that is intended for other applications (swimming pool filters are a favourite) as it will have a different composition (it is heat-treated) and may not be effective.

Uses for Diatomaceous Earth for chickens

1. Removing lice and mites. Diatomaceous earth can be dusted between the feathers and onto the skin regularly. It can be added to dust baths which is particularly useful. Since it is a natural / organic product, it can be used on your chickens. Many other products and louse powders state that they are for use in nest boxes and on bedding, not on your birds. This is because they are not licensed for use on chickens which produce eggs for human consumption.

2. Added to poultry feed – daily use of diatom as a feed additive may result in fewer worms, less mortality and better feathering. There are many different trace minerals contained in diatomaceous earth that are beneficial to poultry. The dose that is commonly used in most animals from poultry to cats, dogs and even cattle is between 2 and 5% (follow the manufacturers recommendations) added to their feed.

3. Other uses – it has a huge variety of other uses from water filtration to cat litter and it is often mixed with grains during storage to prevent mites getting into it and to keep it dry. The other main use I have for it around the home is for an organic approach to flea control on our pets.
