Thanks to all but I think its because the food.
Gave them cheaper rabbit \ hamstring food instead of mice with protein etc' as my breeder friend told me before to do.
The store seller said they will breed with every food ill bring them..

While you do not need to give cheese,veggies or toffu or any supplements (I would not give those to feeders only pets and as a treat not a staple diet, remember cheese is mainly fat), you do however need a food with 18% protein at all time (breeding and nursing as a feeder breeder takes it's toll quickly and requires energy not found in you store bought mice food or rabbit food.
You do not want to go below or too much higher ince high protein diet can cause health issues as well.

A simple bag of Doggy Bag from tractor supply will do the trick over Mazuri. Since using it it the amount of mammoth tumors in both rats and mice as drop to almost zero which was a big improvement.
