In my experience the cockerels had very upright crests and the feathers were more pointed. The females had crests that were more rounded, probably what you were thinking of, from the beginning, but with age they all developed more fully. As this is a breed, that at least here, has diminished from its SOP standards and I am trying to work them back up to standard I can only guess what your birds are like. If you are able to post pictures for us to look at that helps a lot with us making observations and giving feedback. You want to make sure, one of the most important things, is that they have the 5 toes and that they are formed correctly. There are a few pictures on line of what their toes should look like.
