VetRx Poultry Aid is an over-the-counter, camphor-based liquid that keepers use to ease the sniffles and rattly breathing of mild colds in chickens. It is applied as warm drops, rubbed on the head and under the wings, or floated on drinking water. It is not an antibiotic and it does not cure the contagious respiratory diseases that often cause these signs, so a bird that gets worse needs a diagnosis.
Key Takeaways
- VetRx Poultry Aid contains alcohol and camphor with oregano oil, rosemary oil, corn oil and Canada balsam.
- The maker says it is “for the support of healthy upper respiratory function”. It does not claim to treat infections.
- Directions: warm it, put a few drops down the throat at night, rub it on the head and under the wings, and add a few drops to drinking water.
- Sneezing, bubbly eyes or rattling in several birds can mean Mycoplasma, infectious coryza or another contagious disease. Isolate the birds and call a vet.
What Is In VetRx Poultry Aid?
The VetRx Poultry Aid listing on DailyMed (US National Library of Medicine) gives these ingredients:
| Ingredient | Role |
|---|---|
| Alcohol (3.3%) | Active ingredient; carrier |
| Synthetic camphor | Active ingredient; gives the strong vapor |
| Oregano oil, rosemary oil | Aromatic oils |
| Canada balsam | Resin |
| Corn oil | Base that the other ingredients are blended into |
Correction: an earlier version of this article listed eucalyptus, tea tree, fish oil and garlic oil as ingredients. Those are not in VetRx Poultry Aid, and the claims we made for them have been removed.
What VetRx Is Used For
VetRx Laboratories describes Poultry Aid as a formula “for the support of healthy upper respiratory function” in chickens, bantams, ducks, turkeys, geese and game birds. Its instructions also cover:
- Birds with mild cold signs such as sneezing and a runny nose
- Dry, scaly-looking shanks and toes
- Giving the comb, wattles and legs a clean shine before a show
- Birds traveling to and from shows
The camphor vapor may make a bird with a stuffy nose more comfortable, much like a chest rub does for people. That is all it should be expected to do. VetRx does not kill bacteria or viruses in the respiratory tract, and it does not replace a diagnosis or prescribed treatment.
How to Use VetRx Poultry Aid (Maker’s Directions)
These steps summarize the manufacturer’s printed instructions. They are written for bantams and mature birds of a similar size. For bigger or smaller birds, change the amount in proportion to the bird’s size.
1. Warm It First
Use VetRx warm unless the directions say otherwise. Open the cap, stand the bottle in a small pan of water and heat it on medium. Always test the temperature before it touches a bird.
2. For a Bird With Cold Signs
- Put a few drops of warm VetRx, straight from the bottle, down the bird’s throat at night.
- Rub some warm VetRx over the head and under the wings. When the bird tucks its head under its wing to sleep, it breathes the vapor.
- To swab the throat and wash the head and eyes, mix 1 teaspoon of warm VetRx in 1 cup of very warm water (or 1 teaspoon in ½ cup for a stronger mix). Do this four or five times a day and keep the nostrils, eyes and throat clean.
3. For the Rest of the Flock
- Add a few drops of VetRx to the drinking water each time you change it. It floats on cold water, so it gets onto beaks and nostrils as birds drink.
- The warm solution can also be sprayed over the birds with a small sprayer kept warm in a pan of hot water.
4. For Dry Legs
Rub a small amount of cold VetRx from the bottle into dry shanks and toes. Repeat every three days until the legs are no longer dry. Rough, raised leg scales are more often caused by scaly leg mites, which need their own treatment (see our scaly leg mite guide).
| Use | How much | How often |
|---|---|---|
| Drops for a bird with cold signs | A few drops of warm VetRx down the throat | At night |
| Rub | Warm VetRx on the head and under the wings | As needed |
| Throat swab and eye wash | 1 tsp warm VetRx in 1 cup very warm water | 4-5 times a day |
| Drinking water | A few drops on top of the water | Each water change |
| Dry shanks | Small amount of cold VetRx, rubbed in | Every 3 days |
When VetRx Is Not Enough
In chickens, sneezing, nasal discharge, swollen or bubbly eyes and rattly breathing are common signs of contagious diseases. Examples are chronic respiratory disease (Mycoplasma gallisepticum), infectious coryza, infectious bronchitis and avian influenza. These spread through the flock and some leave birds as lifelong carriers. A rub won’t change that.
- Isolate any bird with respiratory signs straight away.
- Call a poultry vet or your state animal health lab if several birds are sick, a bird has a swollen face or is gasping, egg laying drops suddenly, or any birds die. Sudden deaths can be a sign of avian influenza, which must be reported.
- Get a diagnosis before using antibiotics. Many respiratory diseases are viral, and antibiotics for laying hens have egg withdrawal rules that your vet will explain.
Can You Eat the Eggs?
The VetRx label does not give an egg withdrawal period, and it is labeled “for animal use only”. If you are unsure whether to use eggs from birds you are treating, ask your vet or check with FARAD (the Food Animal Residue Avoidance Databank), which advises vets on drug residues in eggs and meat.
Pros and Cons
| Pros | Cons |
|---|---|
| Inexpensive and widely available | No published studies show it treats or prevents disease |
| Simple to apply to one bird or a whole flock | Needs warming before most uses |
| Also useful for dry legs and show preparation | Can delay a diagnosis if used instead of a vet visit |
FAQs
Does VetRx cure respiratory infections in chickens?
No. The maker describes it as support for healthy upper respiratory function. It can make a bird with a mild cold more comfortable, but it does not treat bacterial or viral infections. Birds that don’t improve need a diagnosis.
How many drops of VetRx do I give a chicken?
The maker’s directions say “a few drops” of warm VetRx down the throat at night for bantams and mature birds of similar size, adjusted for bigger or smaller birds. They don’t give a set number of drops based on flock size.
Can I put VetRx in the waterer?
Yes. The directions say to add a few drops to the drinking water each time you change it. It floats on top, so it touches the beak and nostrils as birds drink.
Does VetRx kill mites or lice?
It isn’t labeled for mites or lice. For those, see our guides to lice and mites.
Conclusion
VetRx Poultry Aid is an inexpensive camphor rub that can make a chicken with a mild cold more comfortable. Use it warm, follow the maker’s directions, and don’t rely on it for a bird that is getting worse. Respiratory signs in chickens are often caused by contagious disease, so isolate sick birds and get a diagnosis.
