Very nice corn. I like those colors. I wouldn't buy many pinkys at all. I think my hatchling colubrids were on pinkys for 6-8 feedings max before they moved to mice fuzzys. The mice fuzzys are only about 4-6g. I typically feed them 10-15% of their body weight (sometimes a little more) per feeding. I feed hatchlings every 5-6 days. In your case I'd offer one pinky for 3-4 feedings, then 2 pinks for 2-3 feedings, after that I'd move up to fuzzys. Pinkys don't have as much nutrition as more mature prey so I try to get my snakes off of them pretty quickly.
