Sex wyandotte & bcm

[Brahmachicken240]

If anyone has the time it would be great if you can have a look at these four bantam wyandotte chicks. They are 6 weeks from my third hatch which went a little bit better. Got 4/9 cream legbar pullets, 3/8 bantam wyandotte that I know are pullets. But these four are difficult to tell, I dont know what the colour is called but these are the only ones with that colour.

All four look to be Cockerels
