That's one way to increase the space requirements.
If the female checkered is gravid she managed about 30 live last year (she deserves a year off next year) have you checked with John whether she could be gravid? She was in with the albino checkered and Kenzo, so unless John had put her in with the males...
If you do have 3 gravid females you'll be wanting some space on Sjoerd's table at Donny.
I'm not sure about the female radix I have here, John said that the radix had locked up (brave boy, he's a fraction her size) but so far I'm not convinced she is expecting. Like the Florida blues, this would be a first litter, she wasn't brumated first, and the male is only just mature, so I'd expect slugs.
