Mystery chick?

[everyday_farmlife]

Spring is just kicking off down here and our incubator has just hit day 22.
We had a dozen plymouth rock eggs in there, 10 made it to lockdown 7 have hatched.
6 look like barred rock chicks should and 1 looks very different
I've just messaged the breeder to ask her what other breeds she has as she very apologetic said she may have mixed up an egg or a hen may of jumped the fence, all is good lol
Now over to you, what breed do you think mystery chick *patches* is?

Breeder has;
Purebred pekins.. cuckoo, lemon & buff, maybe gold lace & lemon cuckoo
Silkies .. mixed colours
pilkies ( polish x silkie)
Polish , gold lace & mixed pen which may include blue, cuckoo, white & silver lace
Plymouth Rock
Marans
Araucana
Cream legbar x

Single comb, no feathering on the legs, no crest. I think you can exclude Pekins, Silkies, Pilkies, Araucana and Polish.

Could be a Plymouth rock or Cuckoo Marans cross.
