ISA brown chicks

Do all of these chicks look female? The chick on the top left is one of the larger chicks yet her feathers are not growing as fast as the others.

It is my understanding that ISAs are sex linked. Female chicks are yellow/buff and males are much lighter. All four seem to have dark, rich colored heads. These should all be female.

ISA Browns are sex linked in coloration, so these are definitely all female, because the male chicks are a much lighter color.
