I've had chickens here for 13 years and never have had a bird show symptoms of Marek's. I haven't vaccinated for anything. I don't know whether my flock is resistant or whether they have never been exposed.Any hatchery chicks I've bought, I've had vaccinated for Marek's. Any chicks I hatched here or bought from breeders, are not vaccinated. I have lost 2 Albritton Sussex to Marek's in the last two weeks, and tonight noticed a pullet looking poorly. Obviously it is too late to vaccinate these birds, so there is no conflict there, as they will or will not survive. Get from the surviving birds will presumably be more immune than those which may have descended from the victims, had they been vaccinated. ...
I generally think our birds need to have natural vigor, inborn resistance to disease, else why perpetuate the line? At the same time, I have an investment I want to protect, birds I strongly prefer not to lose to preventable disease. Where is the line?
Wednesday evening, I noticed a young cockerel showing lameness in one leg. By Thursday morning, both legs were paralyzed. I immediately took him to the CAHFS lab at UCDavis for a necropsy. Still waiting on results. I'm terrified that I may lose my flock if it's Marek's. I don't know what else it could be. All other birds are very healthy. All this year's youngsters were in that same coop with him, ages range from 5 weeks to 4 months old.
