I cull rat pinks for deformities and runts from
the beginning and again a week or two later again for size or early temperament indicators. I suppose I can always compost the pinks and continue looking for something that can handle pups and weaned rats. I compost other meat from time to time. It's tough because my two can handle the older culls, it's just those early age culls. :/ It's like trying to find a pet who needs to eat fatty hot dogs and ice cream.
