Muscovy egg turned dark during lockdown?

[sevenchickens]

9 Muscovy eggs went into lockdown on day 31 (because I had one hatch on day 30) it is now day 33 and one just hatched!! but one of the eggs that has been actively rolling isn't any longer and the part where the air sack is has turned dark. Is this blood? I thought for sure with the new duckling bouncing around I'd get some movement from it, but nothing. Should I cull it or wait?

Anyone? I'm not sure if this duckling is ok or if it could be saved from a problem....Help!

I candled it and saw frank blood and it wasn't moving or peeping... I culled it. When I opened it up the yolk sack hadn't absorbed...It was a beauty though. Now I have one that pipped on the bottom!
