The Scoop on Poop Series: Good Poop, Bad Poop and Digestion

Ever thought much about poop? Yes, that's right—poop. Your chickens' poop, that is. What comes out of your birds is just as important as what goes in, and it's time for their poop to start getting the attention it deserves.

Ever thought much about poop? Yes, that's right—poop. Your chickens' poop, that is. What comes out of your birds is just as important as what goes in, and it's time for their poop to start getting the attention it deserves. If you haven't paid much attention to it before, now is the time to start, and if you do regularly monitor it, then hopefully you'll learn something new to look for.

Digestion 101

In the poultry industry, we put a major focus on nutrition. What goes into your birds directly affects everything from performance to mortality to the bottom line of your business, and we monitor and adjust it regularly. But there is a lot to learn from what comes out of your birds at the end of the nutrition cycle—that’s right, poop. It may not be a dinner table topic, but we are here to give you the Scoop on Poop. 



To fully understand the end of the cycle, we need to understand the digestive process in your birds from start to finish.

Birds eat continuously throughout daylight hours and sometimes into the night. Unless you have programmed a growing cycle or routine with your lighting, they don’t really have specific meal times and breaks like we do. That's why they constantly eat and, thus, seem to constantly poop.

When poultry eat and drink, the food and water go from the beak into the esophagus, which carries it down to the crop. Food begins to soften in the crop before it travels to the proventriculus, an organ that uses enzymes to break down food before it enters the gizzard. The gizzard is a more muscular organ that uses small stones to grind food into a paste that can be more readily processed in the intestine. A chicken's intestine has two small, pouch-like places called ceca.

Bacteria in these pouches help digest particularly woody, fibrous or tough bits of food that the chicken ingests. The food takes its time in this section of the bird so the bird can extract as much of the nutrients as possible. At this point, the bird should have absorbed all the good it will from the feed. It’s time to get rid of what it doesn’t need.

The waste travels to the cloaca, which is Latin for common sewer. This is fitting because in birds, all forms of waste are expelled at once in one dropping. This is what you see all over the floor of your house, and it can be the key to knowing the true health of your birds and efficiency of your nutrition.

3 Parts of Poop

The first part is feces. This is the main part of the stool. It is the only real solid part. If healthy, the feces should be dark brown to tan and tubular in shape. It may be straight, coiled or even broken up into smaller yet still tubular pieces. This is a good indicator of a “tight gut.”

Next, you have urates or uric acid. This is the “white cap” you see on the stool. This is a by-product of protein metabolization—birds converting feed into energy. In healthy birds, the urates should cover about a third to half of the stool and have a chalky white appearance.

Then, the last part is urine. This is the liquid or non-crystalline form of urates, and it typically looks like water. In healthy birds, there should be a very small amount that is almost unnoticeable.

Warning Signs

Warning signs can indicate inefficient feed conversion, disease or infection. For feces, the stool should be free from blood or excess undigested feed. If you see either of these, it could be a sign of a bigger problem.

With urates, because the urates or “white caps” are a by-product of the bird converting food to energy, the amount of white caps seen is used as an indicator of how the birds are converting feed. As we all know, feed conversion directly affects your profitability in a flock. If you’re seeing less than a third of the stool covered in white caps, chances are, your birds may not be efficiently metabolizing protein.

Lastly, for the non-crystalline urine, if your birds have loose, wet droppings, this can be a sign that your birds don't have everything they need to actually absorb the nutrients from the feed. If there is a lot of excess urine, it could also be a sign of a bacterial infection.


Pay attention to the amount, size, color and consistency of your birds’ droppings. Write these things down and note what is normal for your birds as well as any changes you see. Change in poop can be an early indicator of illness or stress. As you take notes of what you are regularly seeing, it may be time to take action if an issue lasts more than a couple days.


The bird droppings on the floor of your house can be key indicators of bigger problems. They can also help you fine tune your business, find areas where you can tighten up your feed conversion, decrease mortality and increase performance. 

In this Scoop on Poop video, we discuss what it takes to develop “tight guts” and take a look at real examples of healthy and unhealthy poop throughout the grow out process from a commercial poultry farm.



A tight gut simply means a high functioning digestive system. Healthy, solid droppings are the best way to measure how tight your birds’ guts actually are. When birds have strong, healthy digestive systems and tight guts, your nutrition program goes further, resulting in better feed conversion and healthier birds—not to mention higher profits. So, how do you get tight guts in this antibiotic-free environment? By strengthening your birds’ natural defenses and digestive ability. To do this, you need a powerhouse of probiotics, organic acids and biologically active carbon. Studies show these work in combination to increase bird health and flock weights, decrease mortality, improve immune systems and create better performance across the board in poultry flocks. Let’s break down why.

Probiotics are simply good bacteria that help birds fight off harmful bacteria, like E. coli and Clostridium, that can lead to big problems like necrotic enteritis and dermatitis. If birds have a whole army of strong, good bacteria in their guts, they stand a better chance at winning if and when disease is introduced to their systems. Organic acids and biologically active carbon help open up the cells that absorb nutrients in the birds’ gut. This means they take in more of the good stuff in the feed and grow bigger and stronger as a result, without you needing to increase the amount of food they eat.

These key ingredients are the recipe for tighter guts and a healthier business. We developed Big Ole Bird with these three components to help farmers strengthen flocks from within, without relying on antibiotics. If you aren’t seeing healthy droppings, you might consider adding Big Ole Bird to your nutrition plan. We have heard everything from “you’re our secret weapon” to “you saved our farm” from farmers who use this performer.

Big ole Bird Studies

We love hearing testimonials from farmers, but we also love science around here at Southland, and we wanted tangible numbers to back up the results we consistently heard from the field. We believed so much in the product that we had two different third-party studies done to prove its effectiveness. The results were astounding. In the first study, birds that were given the Clostridium bacteria to bring about necrotic enteritis and given Big Ole Bird saw mortality improvement from 10.9% to 4.7%. That’s a big deal, guys! In the second study, Southern Poultry Research Group compared two healthy groups of Ross 708s. The group given Big Ole Bird saw an average weight gain of a quarter pound on a 38 day bird and a feed conversion improvement of 7 points.

We are so excited about these findings because they mean the farmers we serve every day can see more profitable flocks and better rankings amongst their peers.

Our goal is always to help you, the farmer.

With the absence of antibiotics and the ever-present challenges of environmental conditions and disease, we know it can feel nearly impossible to achieve the results you saw in years past. The solution to loose guts, high mortality and low feed conversion is to strengthen your birds from the inside out.
