My husband and I were working on our chicken coop the day after Christmas. It used to be a hog barn and we "remodeled" one side into a big chicken pen. The hog feeders sat on concrete slabs. My husband broke them up with digging iron and sledge hammer. We then set these chunks on end and "walked" them one be one across to the other side of the barn. We would let go and let them lay down. One the next to last piece, I apparently left go a second later than he did. My right index finger got pinched sideways between two pieces which weighed about 150 pounds each. I had heavy winter gloeves on and said it was just a little pinch. However, after taking my glove off, he said I needed a doctor. We went to our family doctor. I needed three stitches down the side of the tip of my finger. The end of my finger "burst" open a little and left some of what the doctor calls fat pop out the end of my finger. He put it back in and put in two more stitches there. The whole undersided of my finger from the first knuckle to tip looked like one giant blood blister and turned black. It gradually left loose. I still have a part of my fingertip that feels like a "dog pad" and it is hard to use a sewing needle. BTY, my BR enjoy the pen.
