Reverse mottled with a poofy butt?

[JudgeChunk]

I have this hen that was born on May 1st. She kinda started off looking like a penguin and then mottled and then....I have no idea. As she gets older she's more white with black spots. Also her neck and tail are really round and puffy? I got the egg from one of those etsy serama egg bundles. The parents were mottled and frizzle.


Any day what kind of bird this is?

I believe the color is called Exchequer.

In my very non-expert opinion she looks like a leghorn type hen crossed with an orpington.

She’s a serama (very small!) probably crossed with something else.

Ah ok, I wasn't familiar with the breed as we don't have them in my country. Just Googled wow they are cool looking. I have some mottled leghorns and they look very similar to your photo with more black though. I purchased the eggs as exchequer but in my opinion what I hatched wouldn't meet the standard for exchequer. The neighbors have crossbreed hens who come into my yard all the time and their patterning is like your hens.
