Haha good luck brutha. I know the feeling. I actually had thoughts of rehoming Caesar when he was at the peak of pushing too. I wouldnt have but the thought did cross my mind. All the hamburger face nights is just stressful. I honestly do think its the male/female thing. I mean you have tried everything for Phyllis from more food, bigger food, lower temps, higher temps, everything.
This is the the biggest reason i havent gone with another retic yet as i do have an extra cage. I dont want to get a female and have issues with pushing and i dont want to get a male in case they smell each other and become combative during breeding time and take it out on me lol. Although i have seen a lot of videos with people with multiple males in the same room and even same cage stacks and they are fine.
Anyways, good luck man and hopefully this works.
