Yes, I typically find that a few months before the season starts I'll bump the size of prey offered to my females. I've seen over the years that females with slightly higher fat stores (not obese) will recover from breeding and produce healthier clutches. This is a fine line though if they are regularly fed to much then the fatty deposits can and have interfered with proper egg and follicle development. Males also get a little bigger prey item this seems to help given them the energy and stops weight loss that happens during breeding.
