Several countries vaccinate chickens against Avian Influenza and in some cases have done so for 20 years.I have no issues w/ antibiotics but vaccines are a concern to me. However, after having Mareck's issues where the birds suffer progressively for days/weeks, I absolutely will not have a bird w/o Mareck's vaccination so the bird doesn't have to suffer symptoms where the bird spends so much lengthy time deteriorating. If birds can recover from Mareck's I never had onein spite of my vet's optimism to wait & see.
W/ AI the birds seem to pass very quickly seems almost overnight w/o showing progressive symptoms so I personally will hold any opinion till more info comes forward. Also, at what age are the AI vaccines given? So much to research & whose info to trust. If the AI vaccine can be given to hens past laying age I would vaccinate them for certain but if the vaccine absolutely needs to be given at day-old there is no choice in the matter & we live w/ eating those eggs just like w/ hens that were Mareck's-vaccinated as chicks.
I'm awaiting which USA hatcheries will be the 1st to offer AI vaccine once widely approved. I'm amazed Mareck's isn't automatic in hatcheries but customers have a choices to refuse? Private breeders automatically state their chicks are vaccinated & you don't have a choice. Those are my kind of private breeders.
What a world! Life used to be so much
simpler... Going thru certain flock experiences kinda cements our opinions on how we handle future bird choices.
Another view of Gemma w/ unsteady Mareck's legs she kept spaced apart so she wouldn't fall over. We treated the cocci she arrived with fine but the Mareck's was progressive. She was an adorable Blue Ameraucana from a breeder who didn't believe in vaccines, antibiotics or meds of any kind! We had her only about 2 weeks before having to face the inevitable. Losing both Taffy & Gemma we never got another true Ameraucana again. Such sweet birds.
