A few years ago, my mother went to all natural gardening and landscaping. It took a couple of years, but eventually her backyard was a certified natural habitat! She went the natural, or holistic, route because she wanted a safer environment for her beloved dog.
Personally, I think anytime we can subtract chemicals from any equation, we are better off. I will say, I am not against traditional medicine. Whether for pets or people, I believe it all has a place and time for use. Everyone should choose what best fits their needs. Always consult your veterinarian and remember; sometimes the best option is the quickest option and that may not be natural, but necessary.
With that in mind, I did want to investigate more holistic remedies for common flock problems. I found a few things used as daily supplements for prevention of disease and illness, and others for treatment.
Prevention is always preferable and some chicken tenders use herbs as a supplement in food for that reason. Dried/powdered garlic is used as an antibacterial, oregano as an antibiotic, turmeric for inflammation, black oil sunflower seed for digestion, and DE (diatomaceous earth) as a natural wormer. I also found ACV (Apple Cider Vinegar) is often used as a probiotic for gut and crop health.
Many of the above mentioned herbs can also be an aid in treatment for illness, parasites, even minor injury.
Whether you choose a more natural approach or traditional, a little research and a call to the vet can set your flock on the path to wellness.
I wish your flock, and you, happiness and good health!
