ISA brown 3 days old help ?

[Kristinazeck23]

Every spring I get ISA browns from TSC (I get all my other chicks from a local farm but these) and they were marked pullets. One of them has a more yellow head, but orange body. Is it a cockerel? My last batch of pullets (second to last photo) their feathers on wings were turning white too, so I’m not sure.

I think that light one is male but not 100%

It's a pullet. ISA brown is a type of red sex-link, a cockerel would be an all over even bright yellow
