The red color and opaque area where light isn’t coming through the shell looks promising to me, a dud egg should glow green and allow light to shine through. The red means you have some blood vessel development and the shadowy area means something (embryo) is blocking the light. I mostly do quail eggs, little, dark, spotted, so don’t get to see cool stuff the chicken people take for granted, not sure how easy turkey eggs are to see through, not much detail in the picture so assuming they might be a little tough to see veins and movement In as well. Candle again in a few days and see if that opaque area grows, if so, that is a great sign.
