I do hope you have air conditioning.
Mike, I have wild turkeys that frequent my yard. Happy to have them for that very reason. I have no idea if that is enough exposure to convey immunity, but am betting that it is so. I've toyed with the idea of finding a turkey nest in the spring, and stealing a few eggs to finish off in my bator. Of course, I assume that would be considered highly illegal! Which is why I haven't done it...
I start candling at 2 days and usually do so every day thereafter. (not every egg, every day, of course! But as soon as the house is empty = no witnesses!) I snag an egg or two and head to the bathroom with my flashlight!)
I can just see it now, chickens running around in the yard carrying torches! It'd be sure to send your home owner's insurance up a notch or two! Not to mention, what would the neighbors think???
Time for shorts, sandals, and sunscreen.
