yes you will cook it.
you can hatch a sparrow egg by putting on to soft pillows and or putting it on a hankercheif and putting a lamp over the egg and see if you have ant luck with that and another thing is you don't want to put your scent on the egg too much or it sometimes will not hatch
It could be either a hatchling (recently come out of the egg), a nestling (too young to leave the nest), or a chick (as for a hatchling and nestling).
you can die
It depends. Did stay out in the cold for too long? If it did it will hatch but maybe become sick or die in the egg
Yes.
Yes he will die.
obviously unless if its too hot in the area where the egg's located
No. Chickens are warm blooded birds. Just like any warm blooded creature (e.g. humans), if they stay too cold for too long, they will die. If the egg is cold, the chick will die before the egg can hatch. That's why hens sit on their eggs to keep them warm.
The plant can shrivel up and die.
They do if they get left out somewhere hot, or if they die they will dry up too.
no you can not go to the sun , the sun is too hot if you try you would die.
It keeps you from getting cold. You can die from being too cold, but you can die from being too hot also. Humans are frail.
