Jen, I also like the big bowls for gravid girls. I use 55oz. normally and after ovulation I put the JUMBO 104oz. 80% of my girls dive in an don't come out until a day or 2 before their pre-lay shed. It HAS to feel good in that water when we consider how tight some girls get with those extra big ovulations. Good luck with your season. Who's the daddy of your skinny-dipper?
