It seems like it is okay to have several females with litters in the same cage (although someone mentioned the opposite in page 1) so I will go with that. My goal is to produce at least 1 litter each week, so I guess I will need about 12 females and ~4 males to start with? How do you guys keep track of which female you should breed and which female that shouldn't? Let's say I have 1 cage where the breeding takes place, 3 cages with females (4 females in each one) and 1 cage of males (about 4 males). I'm afraid that I will put a female who should rest into the breeding cage. Any suggestions?
