When we have bacon, usually there's a strip of fat which won't microwave very well. I scissor it off and cut it into little bits and add the bacon fat scraps to a laying pellet/hot water mash my girls get morning and evening.
This is when they get their leftover scraps, drained veggie juice, chopped up apple cores, spent tea and coffee grounds, etc. Sometimes I throw in a handful of scratch, BOSS, horse sweet feed, or birdseed.
