It depends. If you want to eat them, they should be refrigerated. If you want to hatch them, you should keep them warm.
If they're fresh, and haven't had the bloom washed off (a protective membrane) then you don't have to worry about refridgerating them (but they only last about 2 ish weeks if not refridgerated) but if they have already been refrigerated they must be kept cold.
They don't. The United States is the only country in the world that refrigerate there eggs.
Cold is fine, there is no need to heat eggs or milk.
# Medium hot and cold eggs .
Yes, but only if they have been kept at room temperature. If you re-chill the eggs, they will get cold, and cold eggs are terrible.
Some cold blooded vertebrates that usually lay eggs are amphibians such as salamanders and frogs. Also reptiles are cold blood vertebrates that lay eggs such as snakes and alligators.
The eggs have a hard coating to protect them from the cold.
cold blooded come from the eggs, warm blooded comes from privates
If they get cold enough, of course they do.
Snakes are cold blooded any they do lay eggs. Also alligators and lizards are cold bloods who both lay eggs. More examples are turtles, tortoises, fish, and crocodilles. If you are wondering what they call cold-blooded, egg laying animals, they are called ectothrems.
Eggs. Reptiles are cold blooded and NOT mammals.
it depends if they got cold, if they got cold they wont hatch, they will be dead
Maybe its too old to lay eggs now or its too cold to lay eggs
Cold water because when the eggs barely start to be bread they are very soft and hot water can burn them.
