Three of my females broke 1000 grams this month and I am starting to think realistically about breeding. My racks hold either 2 12q tubs or 1 28q tub per shelf. How many of you breed in 28q tubs? I know if they get to be a really big girl they should be moved up to thermoregulate but if the plan is artificial incubation and the female seems a good size for a 28q, why not use it?
