When we decided to get chickens again this year from the hatchery we did not get the Marek's vaccine. We didn't know anything about the disease at the time and thought, "Why pay the extra money? We have never had problems with disease in the past." Biggest mistake ever. We had chickens dropping like flies so we sent 2 in to our local poultry lab. Results came back that it was Marek's. This was the very disease that we did not vaccinate for. I understand getting the vaccine wouldn't have prevented the disease, so there was nothing we could have done other than bio security. Unfortunately we did not take that seriously either and went to a sale which was probably where we got it. Well, that was more of a rant than I wanted it to be. Anyway, the deaths have leveled off. The disease is not affected their laying, we have way to many eggs that we don't know what to do with, thankfully. I guess my question is can we sell hatching eggs in the spring? I would never want to intentionally infect someone's flock, but I read that Marek's is not passed through the egg. With my logic though, I thought the disease could be on the surface of the shell, so I thought we could use Virkon S (I did some research) on the egg. I then did some research about how this effects hatching and according to this scientific study it does not significantly affect hatching or survival rates. Should we sell hatching eggs this way? Any thoughts? Thanks for reading this large post.
