I'm sorry to hear that, Suzie. I can only imagine the severity of your situation. The bone removed from my skull is merely internal.
I must admit that I probably would not be willing to wait until Tuesday. And although I have some pets that might be considered "PETA class," I also must confess that my chickens are livestock, albeit lavishly living livestock.
A few more things I failed to mention earlier... I never had this problem tending hogs, goats, or lambs. In fact, my 13 chickens roost in my old elevated hog house. In one corner, they roost above a 3'x4' manure box that I regularly dust with wood ash. Lately, I'm using brown grass and/or spruce needles over a thin ash dusting for bedding/nest boxes. I mulch their run too--it's like walking on a fluffy mattress. And during winter, I'm in there wearing knee high boots, 2 or 3 layers, gloves, a respirator, and a hat. The house is sided with rough sawn cherry, so ventilation is more than ample. I guess I was surprised that all this wasn't enough.
I did check out the N95 cartridges. Organic vapor--these are the same things I wore when I was vacuuming underground fuel tanks. (Yes, I was supposed to have a scout pack but the boss was cheap, the manholes were narrow, and the 8" vacuum induced plenty of fresh air.)
