Feed what works for her and is convenient for you

I'm going to be breeding her in the future and was wondering if it would benefit me and her to switch her over to F/T. I was thinking it would be so during breeding it would be easier for her to feed instead of making her chase her food down and have to use a lot of energy killing it then eating it.
Short answer, NO

Whether they breed or not does not matter when it comes to feeding, all my breeders eat live.
