There are a variety of avian diseases that a chicken owner needs to look out for when raising these birds.

If your chicken develops a disease that is not contagious you’re in luck, but if the disease is contagious this illness can wreak havoc on your flock.

It’s best to catch an illness in the early stages, treating illnesses earlier on will give the bird a fighting chance to recover with treatment.

If your bird is showing signs of suffering from an illness, like foaming at the mouth, it’s important to get in front of this, this article will help you do that.

A bird foaming at the mouth is not normal, the reason behind chickens foaming at the mouth include: food being stuck in the bird’s esophagus, sour crop in the bird (if the foaming is accompanied by a sour smell coming from the bird’s beak) or aspergillosis if the birds mouth is yellow and foaming 

Chicken foaming at the mouth:

Foaming at the mouth can happen because of illness or a blockage in the bird’s esophagus.

If the bird is not showing other signs of being ill it may be difficult to figure out what ailment your bird is suffering from. Here are common reasons behind chickens foaming at the mouth: 

Something stuck in the esophagus:

Birds don’t chew their food before swallowing, they have no teeth to chew with. In addition, their mouths and throats are not big enough to swallow large chunks of food in one go.

Because of this, they have to break their food into small pieces, small enough to be swallowed.

Still, sometimes, birds may eat foods that are too large for their esophagus. A bird’s esophagus is not very large, and foods that are too large for the animal can be as small as a grape.

If the bird manages to get this food past its mouth then the food item may become stuck in the bird’s esophagus preventing saliva from being swallowed.

This saliva can bubble up out of the bird’s mouth, this may also look like the bird is foaming from the mouth.

What to do:

You will have to flip the bird upside down, and get the bird to “throw up” the food lodged in its esophagus.

Alternatively, you can try to massage the bird’s esophagus to get the food to go down. Feeding the bird olive or vegetable oil before massing will help the food go down.

Sour crop:

Sour crop can develop when food becomes stuck in a bird’s crop, over time, this food will break down and ferment in the crop.

If food breaks down and ferments in the bird’s crop then candida albicans will begin to overgrow in the crop. This becomes a yeast infection.

Foam can develop in the bird’s crop if the bird is suffering from sour crop. If this is the case, this foam will move up the esophagus and pour out of the bird’s mouth.

The foam that comes out of the bird’s mouth is acidic and can burn the bird’s insides, if this happens, you’d need to treat the bird for both sour crop and burns in its esophagus and mouth

Other signs of sour crop include: a squishy crop that feels like a water balloon, a crop that does not deflate when it should, a lethargic bird, the bird not eating, gurgling sounds coming from the bird, and a foul smell coming from the bird’s mouth. 

What to do:

There are a variety of treatments that can help remedy your bird’s sour crop.

Treatments include: massaging the bird’s crop, giving the bird Epsom salts diluted in water, giving the bird diluted molasses, giving the bird diluted apple cider vinegar, or giving the bird Miconazole cream, Nystatin, or fluconazole.

Aspergillosis:

This is another ailment that can affect your bird. Aspergillosis is the most common respiratory infection that birds can get. Not only can it affect chickens but it can affect a wide variety of domesticated and wild birds.

This disease develops when a bird inhales Aspergillus fumigatus spores from its environment. The Aspergillus fumigatus spores can be present in everyday, common items such as bread, contaminated litter, chaff, and even feed.

This fungal disease attacks your bird’s respiratory system, namely the lungs and the air sacks. This causes the bird to grow a yellow cottage cheese material in its mouth and this can look like foaming at the mouth.

Other signs of birds having this illness are suppressed growth, shortness of breath, fever, and respiratory distress.  

What to do:

A variety of antifungal treatments can be given to your bird to treat aspergillosis, these can come in the form of intravenous, oral, aerosolized, or topical products.

The fungal plaques can also be removed surgically by a vet.

Note: If you can, taking your bird to a vet for assessment and treatment is recommended

FAQ:

Can foaming at the mouth be fatal?

Yes, chickens foaming at the mouth can be fatal. If the bird has something stuck in its throat, the saliva can choke the bird if not swallowed.

If the sour crop is not treated it can cause digestive problems in the bird which can hinder digestion and kill the bird. Aspergillosis can also be fatal to the bird if not treated correctly and in good time.

Why is liquid coming out of my chicken’s mouth?

If a liquid is coming out of your chicken’s mouth then this may simply be water.

These animals can’t swallow like humans do, they have to tilt their heads back to get water down.

If your pet fails to tilt its head back after gulping water then the water may rush right out of the chicken’s mouth when the bird is up straight.

If your pet’s crop is blocked, and the animal tries to drink water, then the water may not be able to pass the crop and may come out of the chicken’s mouth.

Conclusion 

In conclusion, foaming at the mouth can be caused by a blockage in the bird’s throat, sour crop, or aspergillosis. All of these can be treated and your bird will recover if treated in good time.
