I have recently decided to feed live opposed to F/T, since my beeps have refused F/T more often than not, but will eat live 100% of the time. The place I get my hoppers from is a bit of a ways away, so I have decided to just take one monthly trip instead of weekly ones. In this case, I will need to feed them but am totally lost as to what they eat at that stage.. I can't find "lab blocks" that I have read about, and I've seen things like bread suggested, but what do you feed your live mice/rats? I threw a blueberry in there today and the one I got today went to town, but presumably they can't live off of blueberries.
Also, I'm keeping them in a critter keeper and am not comfortable punching out the top hole for a water bottle so I have a water dish in there..are they capable of using these at this stage? The one I got today is 12g so is probably closer to a weaned mouse.
