all people and all balls are different....
...I fed small to medium rats for all balls....small balls got nice meals and large balls got nice meals not huge meals...but more often if needed....
I threw the rats/mice/asf/gerbils/etc...in the cage....
remember....most balls will slap and grab the rodent right away...you will know ...who eats what and when.....sometimes you get a fluke.....you hear the slap....you write down it ate...and it actually is a miss, a scared ball, and a rat hiding UNDER the snake when you check on it.....and then a day later....a hole in the cage and an empty cage....with a $$$$ out and a rat set to destroy $$$ in the house....be watchful....
sometimes you will open the cage...rat in hand...throw it in...and it will jump out and run.....smarter rat?....
sometimes you will open cage....rat in hand...and the snake will rab you by the wrist.....on either hand....!...ouch.....! (sometimes they let go....sometimes.....!!!!)
I fed small and hopper rats....duirng that peak time of the year that you know they all eat....mediums.....I never fed an extra large rat to a ball.....
IF you know it will eat....you can kill rat....use tongs/tweezers....and feed fresh killed....always start with the worst feeders first....then go on to the better eaters....and kill one at a time....or you'll have a bucket full of dead rats and no eating balls.....
I have brought home 150 rats and needed double...and I have brought home 40 rats to the same group and had 20 left over....you need to know the balls at every time of the year....they change attitude and color all year long....
good luck...have fun....
I fed live for 20 years and lost just one baby ball.....to a small hopper mouse....must have been a wildly, crazy determined mouse.....I have had holes in racks more than I want to count...(plastic screen for raxx is a NO go...use metal mesh /wire)....
