Thanks Deborah. Are 7-11 gram mice considered weanling? That is the weight-range of the mice that I'm feeding him at the moment, starting from the smallest ones.
That's hopper size, weaning are about 13 to 18 grams on average.
I know a lot of people like to go by weight but at that size you can't go wrong with feeding something equal the girth size, just need to learn to eyeball it, after a while it's second nature
