For those that feed medium rats to their big girls: when do you make the switch from small to medium?
I have all of my big girls (1800 to 2700+ grams) on medium rats (although some are taking an extra small rat as well, except in the case of the 2700+g girl who would want to eat me out of the house). But I have 4 sub-adult girls and one of them just pushed past 1000g. I'm not trying to rush her into breeding as she's just about a year old now. But when should I make the switch?
