Trying to figure out a feeding schedule...

[JoshSloane]

Right and wrong......
Hatchlings can be fed more often because they are trying to grow BUT any snake fed too often is just going to blow it out the other end.
If you weigh your snakes more often you can actually see this happen.
I weigh mine weekly before I feed and when I see an animal pooping every week or two and hovering at the same weight it was a couple weeks ago I know everything going in is also coming right out and is wasted.
When this happens, I cut back on either size or skip a week.

I use to and still do believe in offering till they refuse but not so much once they get around the 700ish gram mark.

I have to disagree with this line of thought. We know that there are many different factors that can affect the gastrointestinal efficiency in snakes. Level of hydration, fluctuations in barometric pressure, stress levels and varying genetic profiles all play a role in metabolic and digestive capacity and rate.

Also, nothing is 'wasted' when eaten. Anything a snake eats is going to be digested, broken down and have the nutrients absorbed. Even if you stuff a snake full of mice they are all going to be utilized eventually.
