Coccidiosis in Chicks

A common intestinal disease in chicks is Cocci (coxy) or Coccidiosis.  As explained in the Merck Veterinarian Manual, it is a "protozoa of the phylum Apicomplexa, family Eimeriidae," and "Coccidia are almost universally present in poultry-raising operations." Even in healthy environments, the chicks may have some Cocci within their digestive system, but when it overloads their digestive tract, then chicks may fail to thrive and stop eating altogether.  

Unfortunately, if chicks develop Cocci, the use of medicated starter feed is less than helpful, nor useful in these situations, especially when it involves chicks, because they will usually stop eating. Most chicks and mature chickens can build resistance to Cocci parasites in their digestive system over time if they are raised and kept in a healthy environment. Unfortunately, brooding environments can be difficult to keep clean and "Cocci" free, as the birds are typically eating feed that falls on the floor that mixes with their feces, or are simply eating their own pooh, adding more Coccidia back into their systems. 

Some common symptoms of Cocci are: diarrhea or extremely watery pooh that is discolored or reddish, general listlessness, weak or hunched, feathers are puffed out, less eating and drinking, decreased weight gain, and skin tone that is pale. A sample of their feces can be taken to a vet for confirmation of Cocci.

An outbreak of Cocci can wipe out an entire young flock if not caught early enough and treated. Mature chickens tend to have developed the best resistance to Cocci. The best treatment is prevention with vaccination. Depending on the stage of the condition, there are some treatment supplements that can be added to their food or water.  The best treatment options involve water since the chicks will continue to drink water even if they are no longer eating.  If possible, isolate the sickest chicks so that they are no longer contributing to the infection load in the brooder. Clean out the litter daily, as well as the waterer and feeder with cider vinegar once or twice per day to maintain a healthier environment. Make certain that the brooder is not overcrowded based on the age of the chicks. Overcrowding poultry at any age only seems to contribute to illness in the flock.   

Please note, if your chicks were vaccinated for Cocci do not feed them medicated starter feed as that will undo the efficacy of the vaccine. If they have not been vaccinated for the disease, then using medicated starter feed may help, but is not a guarantee that it will adequately treat the Cocci overload. Regardless, a clean brooding environment is an ounce of prevention to the pound of cure.

Where We Started

We started like many backyard farmers with a small flock of four chickens.  We chose the Russian Orloff. They are a beautiful bird that will lay about 100 to 150 medium-sized light brown eggs in the first year. They are quite hearty for cold regions which I can attest to that when we had many weeks of subfreezing weather that first year we started the flock. However, they do not do so well in the very hot summers which we have started experiencing year after year the past few years. 3-week Russian Orloff Pullet Because we live in an area that is renowned for predatory animals, we built an A-framed coop and run with a footprint that was just big enough for four hens. It was so sturdy, that we couldn't move it without a tractor!  First Chicken Coop The first coop had all the fancy bells and whistles, like an auto feeder and watering cups, electricity to it for lighting, and insulated. Like I said, all the bells and whistles....

2023 Testing with a Few Different Breeds

This year, we will have a few traditional breeds of chickens, but also some that we have never raised before.  The breeds that we have the most experience with are the Heritage Breeds of Rhode Island Red and the Barred Plymouth Rock.  Last year, we also had the Silver Laced Wyandotte, the Easter Eggers, Black Australorp, and the Lavender Orpington, but we didn't get a chance to raise any of them into layers since they were so popular that we sold all of them as young pullets. So, while these breeds are repeats from last year, the hope is to be able to keep some for our flock.  The Splash Laced Wyandotte and the Cuckoo Marans are totally new to us. Also, we picked up a few special order chicks for a family that we may get to try out. The Cream Legbar and the Olive Egger. We only picked up one extra of each of these last two breeds, so health, gender, and survival will be the key to  us having the opportunity to try them out in our flock.  At the moment, the only ...

Summer 2022 Batch

This summer, we pre-ordered 20 chicks with 15 of those chicks being a "mystery" from the hatchery. We think we have the mystery chicks all identified. Rhode Island Reds, Barred Plymouth Rock, and Golden Comets. The hope is to sell most of these before needing to merge them into the flock. However, if we need to merge in order to winter over until they start laying in January, we can do that. We have done it before and have plenty of room in the main coop.
