@ArizonaDesertChicks, the dark hen looks fine. The more reddish ones are, well, too red. Their lacing is not well defined, the hackles have too much red, and the breast looks like its salmon-coloured with strong shafting.

Here's a link to the American Breed Standard.

As opposed to the American (and British) Standard which asks for a "each feather reddish brown with a sharply defined lacing of lustrous greenish black" in the breast, the Dutch Standard actually requires a black breast in males. I think that's the only difference.
In terms of colour the emphasis in the hens is on "each feather reddish brown, free of black peppering, with a well defined outer lacing of lustrous, greenish black and a well defined inner lacing of lustrous, greenish black. The outer lacing to be distinct yet not so heavy as to give a black appearance to the bird in the show pen" for back, breast and tail coverts.
The female neck hackles are to be of a "lustrous, greenish black" whereas in the male neck hackles each feather is to be "black with slight reddish brown edging and reddish brown shafts, tips of feathers black."
Here is an idealized depiction:
