Someone wrote, "if you have Marek's, burn the barn".This is what I've been trying to tell you....ain't gonna happen. Not now. You have Marek's. Not just the birds...you, your house, your land. You cannot un do Marek's unless you take the actions already told to you. Would you really want to sell something that is going to kill someone elses birds? Can you do that with a clear conscience? You really have to understand...you have nothing saleable. You want to sell birds...cull and start cleaning. Order the oxine and you should have the building ready by June. The ground is going to take longer if you can't work it now. Your own house will have to be steamed...floors, anywhere eggs have been, barn clothes washed repeatedly and boots bleached at least, changed out completely even better after all of the cleaning is done.
I am sorry I sound harsh, but this is reality. If you continue as you want, you become part of the problem and you will kill someone elses beloved birds. Please think about this, very carefully.
