How big should my balls be before moving up to "small" rats? Is it correct that they won't need anything bigger than that even when full grown? I have 6 snakes being shipped to me next week. 4 are late 05's and the other 2 are 06's. I know the 05's are feeding on F/T rat weaninglings, but I'm not sure yet on the other two. Still waiting to hear back. Anyways, I want to order a decent supply of frozen rats in the next week or so and I'm debating on what sizes to get. Here's what I'm thinking of ordering...

50 pups
50 weanlings
100 smalls

I'm thinking that should give me enough of the smaller rats to get them worked up to the "smalls" without rushing them too much. What do you guys think. Should I keep them on the pups/weanlings longer or should that be enough?
