How to keep hay fire risk low | General Homesteading Discussion | Forums

So,  we're still getting the swing of having donkeys around, andnow I'm finding myself getting nervous about how we're storing/disposing of our hay.   We use square bales, and stack them in the barn... This doesn't concern me as much as they're totally dry when we get them,  but maybe it should?  My concern is coming down on when weckwan the barn stalls.  The donkeys make a mess of it, end up peeing on what they throw on the ground, and we scoop it out about once /week and throw it on the other side of the barrier of the barn wall.  It's kind of starting to pile up, and I'm curious if this would be a concern for a hay fire to start up?  I've tried reading online articles,  but nothing really has fit our scenario.   This is probably a dumb question, but I lost sleep over it last night, so thought this place would be able to help!  Thanks in advance!
