Bumblefoot in Chickens

Bumblefoot is one of the more common foot problems I hear about from poultry owners. Many people first notice it as a large, swollen, bulb-like growth on the bottom of a chicken’s foot.

Bumblefoot usually begins with an injury to the foot pad. It does not have to be a wide-open cut. A small scrape, puncture, rough spot, or light abrasion can be enough to allow bacteria to enter the skin. Once bacteria enter, infection can set in and swelling may develop quickly.

What Causes Bumblefoot?

Bumblefoot often starts when the skin on the bottom of the foot is damaged. This may happen from:

• Rough roost poles

• Sharp objects in the coop or run

• Nails, screws, broken glass, or jagged metal

• High roosts that cause hard landings

• Rough flooring

• Sharp-edged stones

• Concrete surfaces

• Excess weight on the foot pad

Even a rough roost pole can cause enough irritation to create a problem in the right bird. Overweight birds may be more susceptible because the added pressure on the foot pad can lead to irritation or injury.

Bacteria Commonly Involved in Bumblefoot

Most cases of bumblefoot involve bacteria such as:

• Staphylococcus aureus

• E. coli

• Corynebacterium spp.

• Pseudomonas spp.

These bacteria can be aggressive, and some can also infect humans. Because of that, birds with suspected bumblefoot should be handled carefully.

When handling an affected bird, wear disposable gloves, wash your hands well afterward, and change or wash clothing before handling healthy birds.

Early Signs of Bumblefoot

The key to treating bumblefoot is catching it early.

Early signs may include:

• Swelling on the bottom of the foot

• Redness

• Warmth in the foot or foot pad

• Limping

• Reluctance to perch or walk normally

• A dark scab or plug on the foot pad

• A lump that feels soft at first

If the swollen area is still soft to the touch, there is a better chance of resolving the problem with proper treatment.

If the swelling goes unnoticed, the area may become hard. Once the swelling becomes firm or rock-like, antibiotics alone may not fully resolve the problem, and surgical treatment may be needed.

Preventing Bumblefoot

Bumblefoot is preventable in many cases.

The first step is keeping the bird’s environment safe. Inspect roosts, flooring, and run areas regularly. Make sure all roosting areas are free from sharp objects, rough surfaces, splinters, nails, screws, broken glass, jagged metal, or anything that may injure the foot pad.

Roost poles should not be too high. Birds that repeatedly jump down from high roosts may injure their feet or legs, which can allow infection to begin.

Concrete floors can also be a problem if birds spend a lot of time standing on them, especially if the surface is rough or abrasive.

Treatment for Bumblefoot

Treatment depends on how advanced the infection is.

If bumblefoot is caught early and the swelling is still soft, antibiotics may be enough to resolve the infection. If the foot has become hard and swollen, surgical removal of the infected material may be necessary.

Surgery can be successful when done carefully and properly. The foot and lower leg should be thoroughly cleaned before treatment. The area should be disinfected with a properly diluted iodine solution. Pure iodine should not be used directly on tissue because it can burn and slow healing.

If surgery is needed, antibiotics are generally used before and after the procedure until the area has healed.

Because bumblefoot can become serious and because the structures in the foot are delicate, surgical treatment should be done carefully and only by someone experienced with poultry foot care.

Antibiotics Commonly Used for Bumblefoot

Antibiotics that may be used for bumblefoot include:

• Lincomycin

• Doxycycline

• Amoxicillin

• Cephalexin

The correct antibiotic, dose, and length of treatment depend on the bird, severity of infection, and the specific case. Poultry owners should seek proper guidance before beginning antibiotic treatment.

After successful antibiotic treatment, birds should receive probiotics in the drinking water for 7 to 10 days, or until droppings return to normal.

Recovery and Aftercare

After treatment, the bird should be kept in a clean, dry area while the foot heals. Bedding should be soft and clean. The bird should not be allowed to stand directly on the affected area if it can be avoided.

Bandages or dressings may need to be changed regularly while the wound is healing. The foot should be monitored for swelling, discharge, odor, bleeding, or signs that the infection is returning.

A bird recovering from bumblefoot should be watched closely until it is walking normally and the foot has fully healed.

Final Thoughts

Bumblefoot can become a serious condition if it is ignored. The best approach is prevention, early detection, and proper treatment.

Inspect roosts, keep the coop and run free of sharp objects, watch heavier birds closely, and check feet regularly when handling your flock.
