what breed are my gray chickens ? .

[Duck_life]

lavenders aren't always light

That is a blue, the whole point of lavender is it having dark grey legs and a light-grey-purple feathering.

Let me tag someone who will know the coloring @Cyprus

Agree with @Duck_life Some kind of blue colored bird, most likely blue orpington.

Blue Plymouth Rock maybe? Idk, I'm just guessing.
Beautiful bird though

Not Orpington or Marans, leg color is wrong. Could be a Blue Rock.

Its ....a .....barnyard..grey .....chicken probably not "purebred " anything. Pretty lady though

At least I got the coloring right . Never new of blue rocks? The more you know I guess

Not likely a crossbred coming from a hatchery.

 

[Cyprus]

It's a blue Plymouth Rock.
