Although you can buy chicken breast at the grocery store or as an entree at a restaurant, there may be some things you do not know. For instance, chicken breasts are very different from mammal breasts. Due to that, you might find yourself wondering, “Do chickens have nipples?” Here are some interesting facts about chickens, how they feed their young, and something called crop milk. Let’s get started.
What is a Nipple?
A nipple is a protrusion from the body that is present on both male and female mammals, such as cats, dogs, monkeys, and even humans. However, in the mammalian world, only the females have mammary glands connected to the nipples. From those glands, milk is produced for feeding their young. As such, just because something has breasts does not mean it has nipples, and vice versa.
Do Chickens Have Nipples?
No, chickens do not have nipples. If they did, it would be rather strange. Chickens are not mammals and are born without mammary glands. For that reason, they do not have nipples. The nipples are designed to support the excretion of milk from the body. Chickens, being that they do not produce milk like cows or goats, have no need of nipples.
This goes along with the theme of chickens having an entirely different reproductive system when compared to mammals. Both hens and roosters have cloaca instead of ovaries or a uterus or testicles. It makes sense that chickens birth and raise their young in ways that mammals do not.
Then What Are Poultry Nipples?
If you have spent any time on a farm or around chicken keepers, you may have heard the term “poultry nipple” before. These are not real body parts! A poultry nipple is actually a small gizmo that fits onto a chicken’s water supply, giving them something to peck at to get their water. In other words, a poultry nipple is a little like the drinking bottles on the side of a rabbit’s cage but without a ball bearing to stop the water’s flow.
Poultry nipples are useful, particularly when you want to give your chickens a larger supply of water without them dirtying it right away.
Why Do Chickens Have Breasts But No Nipples?
Anyone who loves chickens will know that there is a part of the bird called the breast. For our feathered friends, the word breast has a different meaning from what most people understand it to be. Breast can also mean chest or the pectoral muscles. In chickens, their breasts are largely made of meat that is used to stabilize their upper body and keep them upright.
Furthermore, the chicken’s breast bone is among the largest in the body. In order to shield such a valuable bone, chickens evolved larger breasts to protect the bones and the body cavity, where all of their essential organs are located.
Do Chickens Produce Crop Milk?
Fowls do not produce milk for their young. Since they do not produce milk, nipples would be a useless feature on their bodies. Generally, mammals are the only animals in the world that have mammary glands that enable them to lactate. Milk is necessary for the survival of newborns, as it is the only thing young mammals are capable of digesting early on.
Interestingly, there are some species of the bird kingdom that produce something called crop milk. Pigeons and flamingos are two species that come to mind. Crop milk is much like cow milk, being that it is a rich fluid composed of proteins, fats, and minerals. All the essential things a growing baby needs to develop healthily. The crop, if you recall, is located either in the chest or, for some birds, in their throat as a small bulge. The purpose of the crop is to hold food before moving it further down through the digestive tract.
Let’s use pigeons as an example. While the mother pigeon is incubating her eggs, cells lining the crop start to change, thanks to a hormone called prolactin. The crop starts to produce milk that is thicker and richer compared to a mammal’s.

How Do Chickens Feed Their Chicks?
Chickens do not have nipples and cannot produce milk, but that does not mean they are not excellent parents incapable of feeding their young. After hatching, chicks do not require food for 48 hours, because they have already absorbed a tremendous amount of nutrition from the egg yolk. Even before chicks are born, they have eaten!
During the next few days of being born, you will notice the baby chicks huddling together to stay warm under a light or clinging to their mother. The mother hen will teach them how to eat and drink. Observe the hens — they will hold food in their mouths. The chicks, guided by their instinct, will peck at the food in their mother’s beak. Sometimes, the mother hen drops little kernels of food into the mouths of their hungry little ones. Even without a hen, chicks can learn on their own when giving starter feed.
When allowed to spend time with a mother hen, the chicks are given a generous diet of commercial starter feed, meat pieces, grains, and insects. Hens tend to know what is safe and edible for their young. You may notice chickens scratching around, searching for worms, for their young. Basically, chicks learn how to survive on their own from a very young age.
Can Baby Chicks Drink Milk?
If you opt to give your chicks and chickens milk from a cow or goat, they can certainly drink it. However, milk is not necessary for a chicken’s survival. Most of their nutrition comes from the commercial chicken feed, along with treats and foraged bugs.
Baby chicks are tolerant to lactose, a kind of sugar present in milks produced by mammals. Fascinatingly, crop milk does not contain any sugars. You can give your chicks dairy products, including cow milk, cream, and even yogurt.
Do not give your chicks or chickens too much milk, however. The sugars and fats present in milk will amount to too many calories. They could grow obese, and that is not healthy. Your chicks and chickens will do just fine with starter feed and, when matured, commercial feed.
So do chickens have nipples? No, they do not. Chickens may have breasts, but those breasts are not made for producing milk. Regardless, your chickens will be incredible parents when their chicks are born. No milk is needed to give your chicks the best life possible!
