Does the strength of the barrier between egg yolk and white indicate freshness?
Often you can plop eggs out of the shell on a pan nicely, so that the yolk remains whole and doesn't leak out to mix with the white. But other times, the barrier between the yolk and the white is so fragile, that there is some disintegration and some of the yolk leaks out when you try to get it on the pan. Also it becomes difficult to separate the yolk and white.
Does this indicate the eggs are less fresh?
I have the eggs sitting in ambient temperature of 30°C (around 86°F for those using exotic units), this is the room temperature. I have a suspicion that this (egg yolk leaking) happens more for eggs which have been sitting more days since collection, but I am not sure yet if there is a correlation.

It can be a sign of lack of freshness, as yes, the membranes will break down the older the eggs are, but it can also be a sign of another type of age or the general health of the bird producing the eggs.

How can identify if the egg is in good quality?
A quick test for freshness is to check if the raw egg in the shell sinks in a basin of water. Fresh eggs stay at the bottom of the bowl while stale eggs stand on end or float because of the large air cell. Other factors such as a weak shell and fine cracks can also cause the egg to float.Does the color of the egg yolk indicate freshness Why or why not?
The short answer is no: yolk color does not indicate freshness. Although egg whites can become "looser" or more watery over time, yolks generally don't lose their hue as they sit in the refrigerator.What do you call the protective coating of an egg in order to maintain its freshness?
The Cuticle: Related to the egg's bloom, the cuticle is a natural protective coating that is the outermost layer of the entire shell. It seals the passage of gases and bacteria inside and outside and signals the formation of the harder calcium carbonate coating during egg formation.What is the outer covering of the egg?
Eggshell is made almost entirely of calcium carbonate (CaCO3) crystals. It is a semipermeable membrane, which means that air and moisture can pass through its pores. The shell also has a thin outermost coating called the bloom or cuticle that helps keep out bacteria and dust.5 out of 6 egg yolks turned out of this colour
