I recently moved my mice from inside the house an outside building that is insulated pretty good. Being so it stays around 50 inside even with the 70's and 80's we are having outside unless I leave the door open to let the warm air inside. I also started them on some lab blocks.
Since the move I have not seen a pregnant mouse yet and it has been over 30days since the move. Any ideas? I also have them in a rack system now and it sort of seems like they are always looking for food even though it is right above them. Do mice have a hard time eating through 1/4 mesh? If I put a lab block inside the cage they start eating it right away.
Thanks
