You see a variation of colours in the trays from the same flock.

There could be a lot of causes for pale shells, but if it happens with the whole flock at once, it could be caused by coccidiostats (nicarbazin) in the feed.

Look at all factors influencing shell colour: disease, age, stress, parasites. But also sunlight has an effect. Eggs from hens with an outdoor run often have an paler appearance that indoor kept hens of the same strain.
