Handling a Contagious Illness in your Backyard Chicken Flock


Of course all of us backyard chicken keepers want to concentrate on hanging pretty curtains in our coops, making fun treats for our chickens and taking pictures for Instagram of our cute chicks surrounded by flowers.

On my Fresh Eggs Daily Facebook page, here on the blog and especially on Instagram, I try and keep things fun and upbeat, but the reality is that the cutesy side of chicken keeping has to take a backseat to good biosecurity practices, proper sanitation and flock management.


Chickens are extremely susceptible to various illnesses and diseases, many respiratory in nature, and many contagious.

Since their body temperature is higher than many other species and their metabolism much faster, bacteria and pathogens multiply extremely rapidly in poultry.

Newcastle Disease, infectious bronchitis, avian influenza, infectious coryza, fowl cholera, and mycoplasma, just to name a few, can be disastrous to your flock. 


Many poultry illnesses can be fatal if not treated, but many can’t be treated – or there are no commercial products specifically labeled for use in poultry.

It can be hard to find a qualified avian vet to treat your flock, and nearly impossible to diagnose a sick chicken, but that doesn’t mean that you are helpless or your hands are tied.

These diseases are not very common in backyard flocks, but prevention is definitely your best best  - and most illnesses can be easily managed by taking a few steps.

Prevention


A flock with strong immune systems and a clean, well-maintained coop and run are imperative, as is catching any problem as quickly as possible and isolating sick birds to try and stop the illness from spreading through your flock.

To prevent contagious disease:
  • keep a close eye on your flock and do regular 'checkups'
  • spend plenty of time with your chickens so you know what is normal behavior and what’s not
  • build strong immune systems
  • keep your coop and run area clean and well-maintained
  • keep your coop and run free from wild animals, rodents and birds who can be carriers
  • maintain sanitary conditions
  • provide clean fresh water and good-quality feed daily
  • adhere to proper biosecurity precautions
  • don’t bring new additions to their flock in without proper quarantine periods
  • practice over-all good flock management
You don't need to use all kinds of crazy chemicals to fight pathogens and bacteria - we only use natural cleaning products and have never had any kind of outbreak of any disease or illness.

For a strong immune system: A daily regiment that includes good-quality feed and clean water is necessary for a healthy flock.

Add to that a bit of probiotic powder in the feed for healthy digestive systems and intestinal tracts, and some apple cider vinegar in the water for overall good healthy and to balance ph levels in the body, and you’ve just increased your flock’s chances for being healthy. 

Go one step further and add some dried garlic powder into the feed or drop a whole fresh clove into the water as an immune system booster and you can sleep at night knowing that you’re providing your flock a super healthy diet.

 The ‘holistic trinity‘ of apple cider vinegar, garlic and food-grade diatomaceous earth is paramount to raising healthy chickens. 


Adding dried herbs and edible flowers to your flock’s feed also provides additional health benefits. Generally chickens will recognize what they need in order to stay healthy, so provide them the tools to build their own strong immune systems.

But preventives aren’t 100% fail proof and sometimes an illness will still take hold, especially  in weaker flock members.

Precautions

At the first sign that anything is wrong – including listless or droopy hens, watery eyes or nostrils, coughing, sneezing, infection, swelled wattles, etc. – immediately separate the ailing bird somewhere safe from predators, warm and quiet.

Be especially careful if you have a sick bird around chicks or young pullets, or broody or molting hens who’s systems are already being taxed. Assume whatever she has is contagious until you find out for sure otherwise.

Consider your flock a "closed flock" until you get a diagnosis. It’s extremely irresponsible to add to a flock that is potentially fighting a contagious disease.

On the other hand, it's just as irresponsible to sell or rehome birds from a potentially sick flock as well. Even if others don't show symptoms, they can be carriers.

Your goal here is to stop the spread of the pathogen to the entire flock.

Until you have a definitive prognosis and know what you're dealing with and that it isn't contagious:
  • Separate the sick bird and keep her quiet and warm
  • Assume it's contagious and that your entire flock maybe infected
  • Do not eat or sell any eggs the sick bird lays
  • Do not hatch any eggs she lays (or any eggs fertilized by an ill rooster)
  • Do not hatch new chicks or bring new birds into your flock
  • Do not sell or rehome any chicks or chickens from an infected flock
  • Tend to the rest of your flock first, then the sick bird, then change clothes and wash your hands well. Many illness are extremely contagious and pathogens are easily carried back and forth between sick and healthy birds.


Treatment

Certain diseases are not treatable.

 Ultimately, if the chicken can’t muster and fight off the pathogens, sometimes culling the sick bird (or sadly your entire flock if the disease has spread) is the only option.

 But before you take any drastic measures, take steps to strengthen your flock’s immune system, try to find a qualified vet and follow their prescribed course of action, and practice good biosecurity measures and quarantine procedures.
  • Drizzle some molasses over her feed as a toxin flush and nutrient-packed supplement
  • Offer a bit of plain, unflavored yogurt and some fresh (or dried) oregano
  • If you decide to treat your sick bird with any type of antibiotics or commercial medications, be sure you know the ‘withdrawal’ period (length of time after you stop medicating during which eggs are not deemed safe to eat).
  • After you have successfully eradicated the illness (or, sadly, lost or culled the sick chicken) thoroughly clean and disinfect the coop and run area
  • Have dead birds tested at your state avian lab (some states require this)
Infectious diseases shouldn’t be feared or keep anyone from deciding to start a backyard flock,  and hopefully you will never have to deal with any, but knowing the potential risks of not keeping your flock healthy is paramount to any chicken keeper.
