Do chickens pee?

By Chicken Fans Editorial Team

Chickens don’t pee or urinate, but they do have kidneys that produce urine. It’s one of the most common questions we get, so let’s tackle it once and for all.

Do chickens pee?

Chickens don’t pee with urine streams as they have no bladder or urethra. Their kidneys produce urine with uric acid. This urine leaves the body with droppings via their only opening, the cloaca. The uric acid crystals form a white deposit on chicken poop.

The Chicken’s Urinary System

Overview of chicken kidneys with the veins and aorta, the long kidneys and the two ureters going to the cloaca

Like most birds, chickens don’t have a bladder. However, they do have two long kidneys that produce urinal waste.

The kidneys remove waste and toxins from the chicken’s blood. While mammals convert nitrogen to urea and store it in the bladder, the chicken’s kidneys produce non-water soluble uric acid.

The urates with uric acid end up in the urine and travel directly to the chicken’s cloaca via the ureter.

When the urine arrives in the cloaca, it travels back to the large intestine, where the body reabsorbs the water of the urine.

With the water removed, the urine becomes thick and pasty. It’s then mixed with the digested food in the cloaca. The urine and poo are passed in a single dropping where the uric acid creates a white deposit on top of the poo.

Next to their urine streams, chickens can also fart, which is a normal occurrence in their digestive process. But excessive or foul-smelling gas may signal underlying health issues.

Chickens don’t have a bladder, and their urine leaves the body with droppings. Chickens also don’t sleep in their nests, they roost on a roosting bar. They do, however, still drop poo at night. So hens that sleep in the nesting boxes will, in a sense, pee in their nest.

Do chickens pee and poo from the same hole?

Yes, pee is mixed with poo in the cloaca and leaves the chicken’s body via a single vent opening. In fact, the eggs of laying hens also pass through the same opening. When a hen is laying, its vagina folds inside out to separate the egg from the droppings.
