No need to ever do a mice vs rats for males as it wont make or break their fertility. The females is what causes this and with 30 eggs in incubator from all rat eaters and their just fine.

Her being only mouser has 2 years in a row where her eggs go down hill..

Thats plenty proof right there if i can get a good clutch on her 3rd time while being a rat eater.
