After listening to an interview in which three herbs were mentioned as great for chickens, I did a bit more research and found that these herbs are also beneficial. I'm sure there are many more; however, this is a great start, with many of us already growing many of the herbs in the list below. I will start with herbs to avoid, and as always, if you're unsure about a herb, do a little more research to confirm. HERBS TO AVOID as these can be toxic: onion, chives, and lemongrass. HERBS TO USE: - Thyme: cold and flu, antiviral and antibacterial - Oregano: digestion - Mint: digestion, heat stress, boost the immune system - Parsley: a good source of Vitamin A, C, and K, boosting the immune system and supporting bone health - Basil: antibacterial, can repel flies and mosquitoes - Sage: an antioxidant that is thought to help reduce the risk of Salmonella infection - Rosemary: aids in pain relief, respiratory health and aids in repelling insects - Calendula: helps add colour to egg yolks, is anti-inflammatory and can be used for wound health - Lavender: has a calming effect, helps relieve stress, repels insects and flies - Coriander: source of Vitamin A, C, and K. Seeds are a good source of antioxidants and have anti-parasitic properties - Wormwood: helps to deter internal parasites and external pests like flies and mites, can aid gut health, studies have also shown to help with issues like coccidiosis and heat stress and when appropriately - Mugwort: acts as an insect repellent, deterring pests like mites, fleas, lice and potentially as a supplement for gut health and parasite control - Nasturtiums: natural antibiotic I'm sure this list can be added to. Herbs have wonderful medicinal properties, obviously for our chickens as well as for us. HOW TO USE HERBS: - Fresh: hang fresh bundles in the coop to allow chickens to peck at them, or mix fresh leaves into their feed - Dried: Dry and crush herbs, then mix them into their regular feed - For specific needs: place Lavender bundles in nesting boxes to promote a calm environment :-)
