One note, crele is sex linked barring on e+, aka red duckwing/black breasted red. maybe partridge in the UK? (USpartridges are different- eb aka brown base).
It's extremely common for people to name or sell barred birds showing any color other than black/white as 'crele'. This problem is particularly bad with US polish, all so called crele polish so far are blacks leaking brown color on hackles and no duckwing patch on roosters or something like very mixed pattern showing traces of gold lace.
If red duckwing does not exist in said breed or project, it's very likely they are mixed color rather than true crele. It seems merely adding 'crele' to the name generates a lot of interest though...
