I've had a damn phlegmy cough since january one lot of anti biotics did'nt shift it, so have put up with it, but i have noticed it being worse when I go in the pigs shed and use the hay, hope its not because of that, might have to use something else in my runs instead of hay maybe fleeces, cant imagin it though as the girls would pee it soaking wet the first hour of putting it in, any ideas?
