It might happen quickly or it might take a couple of days.Will the death happen within an hour because I candled the cracked eggs and I saw veins (Or something that looked like veins) moving?
You're going to want to get a couple more chicks to keep your single chick company if it hatches. Candle it too to make sure it doesn't have any cracks in it. You might want to abort this hatch and try again with at least half a dozen eggs if you can't find any chicks locally.
