Chickens are omnivorous animals which means that they can eat both plants and animals. It's in their nature to forage and when allowed to free range, they will naturally come across varieties of wild growing herbs. But it doesn't need to stop there.

A number of common herbs can be grown for chickens to help bolster their overall health. There are also many herbs that can be administered medicinally for specific health issues. For example, specific herbs can also be used to treat chooks for infestations of worms, lice and mites. We've discussed each of these in more detail below.
