I think it depends on what your goals and intentions are with breeding. I'd say plan ahead and if you think that you're going to continue breeding then get a rack. You can go with a vision rack which would allow for the ability to have hatchling size tubs as well as slightly bigger tubs for growing your holdback animals too, all in one rack. My first season I had 4 clutches (33 babies) and 12 clutches (80 babies) in my second season. Luckily I bought a hatchling rack. Good luck.
