Little turkeys are very likely to pick at anything that shines, inclding each other vents..I have had brand new babies pull out anothers insides. Make sure you have plenty of things to draw their interest to peck at. I put the little glass stones around in the bottom of the brooder as well as in the water and feed. I decorate the sides of the brooder with little polka dots. They just love walking around picking at all the little bugs on the wall. They loved some old bead necklaces I restrung and hung into the brooder. Once the picking starts, if it starts, you must separate any poult with even the slightest injury.
