How do you tell if a duck egg is bad?

Answer 1

my son found duck eggs in a wheat field they were burning. the hen was sitting, but he got them so they would have a chance to survive. I put in an incubator but some of the eggs are dark under the shell are these good eggs?

Answer 2

You can tell if a duck egg is bad by gently placing it in a bowl of water - if it sinks and lays flat on the bottom, it is fresh. If it stands upright at the bottom or floats, it may be bad and should be discarded. Check for any unusual odors or discoloration as well.

Answer 3

Shine a light through it and count the air bubbles

(air bubbles r methane)

More methane means it is bad.

The best way to tell if a raw egg is off is to place it in water. If it is off, it will float. If it is good, it will sink entirely. If it is old, but still edible, it will position vertically in the water, with its blunt end up but its pointier end touching the base of the bowl of water.

Answer 4

Eggs if you put them in water and they float, they are bad. If they sink, they are good eggs. That is how you tell if they are bad or good. I would throw them away if they float. Or hard boil them and grind them up and feed to your chickens. They love it.

Answer 5

put an egg in water if it dose not go down it means bad egg

Answer 6

check if there are any cracks on it or see if a green crust starts to layer on the outside of its shell or shake it and if it makes no sound than its bad

Answer 7

I think that you hold an egg and flash a flash-light at the egg and you can tell if it fresh or not fresh.

Answer 8

Not sure which country you're in - but - in the UK, each egg is printed with a use-by date on the shell.

Answer 9

If you can't remember when you bought them, chuck 'em. Buy a fresh bag for a buck or two. Live large.
