How did i end up with a gray chicken?

[I Like Turkeys]

Hello, i’d genuinely like to know.
Back at the end of November/start of december, 2021, I hatched 3 eggs from this hen-

Two turned out mostly white, save for some red leakage on one and black leakage on the other, but the third turned out gray, as shown below. She lays off white eggs, also shown below-

I am very confused on how this happened, as none of the roosters who could’ve been the father at the time looked gray. All the roosters who could’ve been the father are shown below-

The dad was one of the EEs, I'm guessing probably the last one. The gray color came from him.

Most likely because when you breed a white bird to any other color you get Whatever color genetics are hidden under the recessive white. What you showed as grey is blue most likely your hen has blue in her background somewhere along the way.

Then hen is clearly Heterozygous dominant white, it could be a California White(White Leghorn x California Gray), White Leghorns can hide blue and barring and even mottling. The F1 female offspring will be Blue/Blue Birchen
