Maybe your girls are producing less eggs.... could be the reason for smaller litters.
My Lucy used to produre 4 pups per litter... then she producing 2 in a few litters... I had her spayed at 5 years old... the vet said she had cysts on one of her ovaries (nothing dangerous)... he said her breeding days would have been over soon anyway... even if I didn't have her spayed when I did.
