Does anyone have any advice on guppies? I have a lot and have had the tank for a while, however I think they are still eatting a lot of the fry.

My goal is to raise as many as posible to adulthood. I will try to upload a picture to show how many plants I actually have in there. I recently placed a female that looks like she is due any day in a breeding bow that I finally bought. Do you think it will help? She has been in there for almost a week because she was really boxy and gravid. Will this stress her so she doesn't give birth? Let me try to get a picture of her too...
The next 2 pictures show the how heavily planted the tank is and the breeder box in the upper left
These 2 pictures show the female that I think is due soon. She has been in there for a week like that and still hasn't dropped. Should I be concernered or should I remove her?
