I recommend Dr Z at the Duarte-Azusa Animal Hospital whenever someone asks. He's been my chicken vet for over 4 years and only 10 minutes from my house! But that's not why I go to him! He sees dogs/cats/exotics/birds and worked in the poultry industry and can identify a problem with one of my chickens just checking her over for a few minutes. He is very thorough and has helped to save my little Silkie with CRD issues more than once! The Park Rangers bring him injured foxes, deer, turtles, lizards, etc. He's performed surgery on chickens, dogs, cats, wild birds, rabbits, guinea pigs, you name it. He doesn't send you to a surgeon specialist that cost more $$$ -- he does the surgeries himself. He won't waste your $$$ on blood tests and necropsies unless you insist on them. I have never trusted an animal vet so much as Dr. Z and my friends have started taking their pets to him too. So glad you had the chance to experience him as your chicken vet! He took photos of my Partridge Silkie hen to email to his wife last time I was in! They are real animal lovers!
