Howdy...
Rodents are just fine.....it's the size that's important.
For instance...my 7-8 footers only eat small rats...but, may eat one every other day.
They're very active snakes by nature and, that trait.....makes keepers want to over feed because, they're always looking for food.
You can feed a black head everyday......but, only the smallest of meals.
The last thing you want is a over fed animal that just sits in the cage.
Animals that have been 'power fed" or to "get up to size" have a reproductive cycle for only 3 or 4 years..... before they burn out.
Womas handle rodents much better but, it's not really a good idea to over feed anything (imo)
Cheers,
