they eat bird egg
Nothing, as long as it is not rotten, it is just like eating a chicken egg. A chicken is a bird.
It eats bird's egg,lichens,mosses generally.
probably NOT
The tried and true method is to hold the egg up in front of a bright light; a chick inside would appear as a dark spot inside the egg. Otherwise, by looking at it, you cannot tell. If you weighed it over time, the egg would become lighter if a chick were developing inside it.
Yes, bird's eggs will always have a yolk, for example, the eggs that we eat has a yolk and the chicken that layed the egg is not mated.
Chickens will eat their own eggs.
An owl is a bird and no, no bird eats an owl.
cook them, and eat it. ;)
you will probably get sick
Most defintley, especially if it is a baby eagle, or an egg. A cat may be lucky to catch an eagle, but a large cat would have no trouble. Almost any bird or creature would try to get an eagles egg or baby also, including probably the crocodile.
