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.
Sea star eggs have more yolk compared to frog eggs. Sea star eggs are considered macrolecithal, meaning they contain a large amount of yolk which is necessary for the development of the embryos. Frog eggs, on the other hand, are typically microlecithal and contain less yolk.
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
Less than half of the eggs turn into tadpoles in frog reproduction because many of the eggs are not fertilized by sperm. Additionally, some of the fertilized eggs may not develop properly due to genetic abnormalities or environmental factors. Only the healthiest and most viable eggs will successfully develop into tadpoles.
Gray eggs in bird species are significant because they often indicate a camouflage adaptation that helps protect the eggs from predators. The gray coloration helps the eggs blend in with the surrounding environment, making them less visible and less likely to be targeted by predators. This adaptation increases the chances of the eggs successfully hatching and the offspring surviving.
Robins. Also, less common species of chickens such as the Araucana and the Ameraucana produce interesting colors and patterns of eggs.
Humming bird eggs are the smallest type of bird egg. They are usually no bigger than a penny or dime.
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
It depends if you mean common garden frogs then 3-4 weeks
