So I had to clean the meat coop because it was getting pretty gross and outta hand in there due to our run not being finished and the birds being kept indoors I had put some DE in there a while ago in my attempt to try and hold them off for a cleaning. Since that was awhile ago I completely forgot about it (and my kids tore up my mask, they are 1 & 2 years old) anyway, It started a couple of hours after i cleaned the coop. The first time this happened I didn't even know why i was coughing until I came across this thread and coughed for three days... now i recognize it. and its because of the DE. Is this cause for concern. Should i do anything about it?
