If I were you, I'd just get 100 from rodentpro.com or someone online.
for instance: I have 9 new hatchling snakes I bought this summer and about 15 normals I hatched myself this summer. Even though I plan on getting rid of the normals ASAP, I bought 400 pinkies to get me through to decemberish.
the math I did:
9 snakes:
2-Anery A's eat 2 pinks each every 3-5 days
2-Miami's eat 1 pink every 3-5 days
1-Motley normal (het crimson) eats 2 pinks 3-5 days
1-Striped normal eats 2 pinks 3-5 days
1-non eating motley normal
lets say they get fed twice a week. Thats 14 pinks per week, 56 pinkies per month and about 200 pinkies in 4 months.
BUT I also am trying to get my normals to eat normally so they can be sold
My Normal Hatchlings = 14, only 4 or 5 of which are on f/t, the rest either don't eat or eat only live (or DAMN ANOLES *grunt at June hatchling*)
Just do the math and remember, many small meals are usually better than single massive meals. They're typically easier to digest and provide more sustenance for the snake. Don't worry about buying too many, the great things about snakes is they'll eat smaller stuff too. EXAMPLE: My adult breeder gets left over uneaten live pinkies that my damn hatchlings won't eat. She's almost three years old and still loves a pinky snack.
Just feed more if you think they're too small. It never hurts at $0.17/pinky.
