VetRx is made from Canada Balsam, Camphor, Oil Origanum, Oil Rosemary, blended in a corn oil base.
We use equal parts of eucalyptus, rosemary, and oregano oils mixed with distilled water when we don't have VetRx.
ACV/Cayenne for Respiratory
3/4 cup apple cider vinegar
1/4 teaspoon ground cayenne pepper
1/2 teaspoon salt
Place all ingredients in a microwave-safe glass and microwave on high one minute. Stir well. Your salt should dissolve into the vinegar but the cayenne pepper won't. If you want, you can strain the pepper out, or you can leave it in. Either way, let it come to room temperature and then add to a gallon of water. This is your chicken's drinking water. (Note: you can administer this on a regular basis, but if you do, just don't add the salt every time. It is not good for your birds to continuously consume salt water, and you should only use it as a treatment.)
