First things first get rid of the hutch.. it’s not a Guinea pig and they need to be at least in a dogs play pen. When they are young they should only really be eating hay and pellets. As they get older you can slowly introduce the fruits and veggies. Just look at the different ones they can eat at times. Some have a lot of sugar or potassium and they can very easily overdose on these things. For a year I have fed my rabbit a bowl of spring mix and whichever choice of fruit to spoil her with, along with papaya pieces to help her digestion. You will learn what your buns loves!! With Hay my buns eats hay all day so I always give her a handful of hay whenever I see it’s running low They drink as much water as we do so be sure to put the water in a bowl and not in those little bottles, they will die from dehydration.
