What size mesh does everyone use on their mice setups ? I ask this because 1/4in (6mm) seems way too small for them to feed through but 1/2in (12mm) seems great for feeding but the hoppers squeeze out 
When I used plastic boxes I had 1/4in top that had 1/2 troughs to feed from and as long as the trough was kept filled up the hoppers couldnt get out, but now that I'v changed over to a tray / rack system I'm having a few problems of escapee's with the bigger size mesh.
As you can see from the photo I am using both size's of mesh but in the cages with the 1/2 mesh the mice were used earlier so that I had no escapee's. I changed over to trays because this method of keeping mice is not space effective and space is one thing that I lack.
