The larvae inside frog eggs are able to get their own nutrients better than birds. Therefore, they do not need as much yolk for nourishment.
The eggs of the Pacific Tree frog produce three times as much photolyase as the eggs of the Cascade frog, making them less likely to die as a result of exessive ultraviolet light.
Frog eggs, because a sea star develops faster therefore needing less yolk for development and being able to feed sooner than a frog.
One is more likely to find lots of frog eggs in a pond with a small amount of fish because frog eggs tend to be eaten by fish sometimes. So less fish equals more eggs that survive.

The bigger the bird the less eggs just for the fact that big bird babies (say that 3 times fast) are harder to take care of and require more food to grow then smaller bird species
If you incubate them, probably about 2-3 weeks. If you do not and let your bird handle it, then probably no less than incubating the eggs. -Kynlee Bird Expert
Frogs are fertilized outside of the mother which is part of the reason half of frog's eggs turn into tadpoles. Also, predators nearby may be drawn to the eggs.
Robins. Also, less common species of chickens such as the Araucana and the Ameraucana produce interesting colors and patterns of eggs.
Proportionately less, yes.
A female single bird like hen can lay eggs with special feed or otherwise but you can not get chicks out of them and number of eggs would be less
Humming bird eggs are the smallest type of bird egg. They are usually no bigger than a penny or dime.
Because...... many birds live their and theirs not as many rats and ferral cats that can eat their little baby eggs. With rats and cats earing the baby eggs it causes a less population of these little birds
