Ooooo that's awesome I'll have to look into what she can spare. Yes the mortar tubs are the cement mixing tubs which are 27x24x6.5 tall... I was just wondering if the 6.5 tall would be an issue. The small litter pans are approx 14x10x4 tall. So ideally you would want to throw a male in with 4 females for about a week, pull him and then let the females pop and then after weaning and waiting a week or two throw the male back in for a week? Could I house multiple males together or would it be better to just rotate 1 male through like 5 or 6 racks or would that just be over kill on a male always breeding?
