I'm getting a little discouraged at rat breeding, they're not producing the way i thought. this was supposed to be easy. I'm sorry to keep complaining but i've followed the advice given by plenty of experienced breeders. we've added dog food to their diet, left them alone, the only time we bother them is to clean, add food & water on every friday, other than that when i get home from work in the mornings i toss in a carrot in each tub and they will not be bothered at all after that. anyway one of the females was HUGE, i mean she was outta control huge, when i went to toss in a carrot tuesday morning it was visible that she gave birth, so i let her be, then wednesday morning when i tossed in the carrot i took a quick look and there were noy even one alive, all i saw was 2 dead. this is not the same female from my last complaint. am i the only one with bad luck? could the females just not be good breeders?
