I use cooking oil and dip the legs because it's easier than applying Vaseline. With that said, do it every day until the legs look completely clear. And I apologize for not answering your other question about VetRx...personally, I wouldn't waste it on scaly leg - just applying oil will do the job.Do you know how often I should be applying the Vaseline? I did one round on everyone last night. Then re-applied to my roo mid day since he looks the worse and then got everyone again tonight.. I assume that should be good for a few days?
