How long?

[nitter]

If a chick dies in the egg, how long will the blood veins be visible for? My incubator overheated... I'm not sure if any of the eggs are still viable. It's been back at proper temp for 24 hours and I can still see veins in at least 1 egg

They won't go away for awhile but if it does die the veins will turn a darker nastier color
