What is this chicken? I'm a newbie

In that case, the earlobe color means she is probably still a mix of some sort, but the legs are the right color for a Leghorn who plays in the mud

Yea i think so . She's not pure, mix bloodline.
And she's keep laying eggs till now. Only incubate 1x a few months ago. Is it normal?!
What i know, hen will incubate when has 10-15 eggs

Earlobes look white to me. Hence the white eggs.

So, Does that mean she's a true buff leghorn?

To me they look.... white? Why did I think they were red? They do look white now.

Then maybe she's just a normal Buff Leghorn.

But when I look at it, it's not as white as what I saw on Google or YouTube

That is always the hard part about trying to see colors on anything with a screen!

At present, I think I see white earlobs (even though OP said "red earlobes" in the first post) and willow legs (but OP said they are normally yellow, just muddy at present.)

So it could be a Buff Leghorn that has been playing in the mud.

Or it could be a part-Leghorn mixed breed, because a mix can have just about any traits, depending on what it was mixed with.

In my village. Chickens are bred for laying eggs. In one hatchling there are many colors. Brown, white, etc. Coincidentally mine is the color like in the photo.

Yes, normal for some hens.

Also normal for some hens.

Some hens are very different than others.

Then your chickens are not pure breeds. Mix chickens can be very good, but they are not Buff Leghorn or White Leghorn or other specific breeds.

I think NatJ is right. The most likely explanation for a chicken that doesn't exactly match any particular breed criteria, is that they are a mix of different breeds.
