Same breed, different colored eggs?

[ash_en_em]

I have 4 pullets (two black australorps and two blue australorps). My two blacks have been laying for three weeks, consistently providing an egg 6 days a week. My big girl consistently lays these beautiful brown eggs. The other lays light brown eggs.

Are one of my blacks a cross breed? Or is it normal for each one to lay an egg of a different shade of brown?

My big girl is on the left (the one who won't be bothered to look at the camera because she loves cantelope). She is the brown layer. The one on the right is my light brown layer.

Here are the eggs...

Thanks in advance for any help

Does your big girl have yellow foot bottoms by any chance?

It's pretty normal for chickens to lay different colored eggs, even if they are the same breed. They look pure to me.

They all have pale yellow bottomed feet. Even my blues.

I should also note the is about a week's difference in age between them

Then they're probably Jersey Giants. Still all the same breed, though.

Really? I didn't know Jerseys have the blue/emerald sheen in the feathers too. Do Jerseys come in a blue also?

It's normal.
I had a wyandotte that laid almost white.tan eggs while the otgers laid tan-brown.

Almost all black breeds come in blue as well, as it's just a mutation of black.

No idea about the sheen to the feathers, but JGs have yellow skin, and Australorps have pink skin. Most people differentiate the breeds by checking the bottom of the feet.

After looking at Jersey Giants, they very well could be. Australorps and Jersey's look so similar! Even as chicks! All of my girls are absolutely huge. I mean big lol. And my blues look just like the blue Jersey's I just saw on google.
