Hi I have had a hay roll out with the slow feeder net on it and after all that rain its pretty wet. I did put a tarp over it but the little buggers just pulled it off. At night when they move paddocks I cover it again. I was wondering if I should be worried about mold or how I can know if its gone bad. I put my hand into it tnight and its a bit warm so have left it uncovered. Am I better to not have the slow feeder net on? Does anyone else use their nets in winter?
