Saw this acted out today at Medicine Lake NWR up here in Montana. HUGE snapping turtles and very smart mama gadwall with her babies. Fascinating to watch the little ones already in formation, swapping out tail spot, which might be rear guard, not sure. Thank you for the fascinating video!
Yes, those can be planted. Seed potatoes from a reputable seller will typically be treated to prevent disease. To sprout potatoes, you can simply place them in a sunny spot. I re-use disposable coffee trays in a window sill.
