feeder mice

[Snakefood]

ok, it's been a long time since I bred mice and in the beggining of Oct I got myself a 1:4 colony so I could supply my own pinks for Khuno.

So far not one baby or obvious pregnancy in the bunch! No visual sign of birth and/or cannabalism, (ie: not one spot of blood in the entire enclosure)

So what's my next step, I checked sexes tonight and the ratio is definately 1:4, but I can't see testicles on the male. I can't remember whether mouse testes are visible or not.

My first thought is to replace the male, but wanted some more input on what you all thought??

Much appreciated!!
