honestly, all you need is one male and 1 female, or 3 or at the most if u need lots, feed them mostly hay and grass (alfafas great for the females when breeding) and abit of dry food on the side and itll be sound. I used to breed em as a kid but only have two adults now, one just roams the garden (goes off its food when stuck in a cage) and it eats mostly grass and hay and abit of alfafa sometimes and as i said some normal food. If you wanna be extra nice carrots, cucumber, apple, and bread/toast is great for em. If you get a good breeder youll get 8/9 possibly more a litter and can have 3 litters a year each at least, but if kept in great condition alot more. If you dont want all the ****, keep em in an oudoor pen with a hutch with sum hay in the hutch for em, you'll never have to pick up a **** again as you can move the pen about
