You and many others probably won't like this very much, but, I can tell you from experience, it is better to remove a few females than to have an over-crowded garden. Believe me, it really hurts when you pull them, but it is well worth it. I was told this by an experienced grower many many years ago and really had my doubts at the time (as I'm sure you will), but, he was dead on. After trying it both ways, I discovered that overall yield is much better if the plants have adequate space, as opposed to more plants that are crowded. It's up to you, but I believe in the end you will figure it out also, even if you have to learn the hard way as I did.
(And they're going to get a hell of a lot worse than they are now.
