Its working wonderfully, all the platynota and radiata that came without pyramiding, still have none, the others havent gotten worse. I've got a 7/8 inch female platynota (assumption here of course, but steady 89 incubation + a couple extra scutes) that is giving me the issue, I'm thinking about moving her outside to greenhouse. She doesnt tolerate others, so she is taking an entire PVC enclosure herself. Out of the half ton of platynota i have , she is the only aggression i see (she also grows at 3x the rate of others). Wondering if I'm seeing what we see in some geckos, aggression from high temp incubated females.I say, let any tortoise live in them as long as you can. Mine started getting unruly and too big to be inside around 8 inches and that is when I finally made to the move to outside full time. At that time I had 6 females in one 4x8 closed chamber, enclosure and 8 males in an identical 4x8 foot enclosure. They had been spending lots of time in their outdoor 8x28 foot enclosures, but I always brought them in at night, or left them in in inclement weather. I keep their night boxes humid and set the thermostats to 80 degrees, and I have 65 watt flood lamps for basking on cold winter days. The flood lamps raise ambient temp in their boxes during each day too. I don't use the heat lamps outdoors once temps are in the high 70s or greater. I waited until the females were over 3000 grams before allowing the males access. The males never fought and got along well in their bachelor group. Over the years I have witnessed two instances of one adult female mounting another, but that is the only display of dominance or aggression I have ever seen with the whole species.
