I have a big sterlite brand plastic bin that I’m setting up for my brooder. I was planning to put the foam shelf paper under pine shavings ... so the little chic feet don’t slip all over... question.. I have a “rent a coop” heating plate I plan on using at an angle so the babies can get close or not “as close”... as needed.... but question... will it be safe to use as such? Like not melt the plastic tote or shelf liner ?? Have never used yet.. thought I would ask other users... thanks!!!
