Hiya!!
Ive learnt from here that too much rich food isnt good for baby buns.It can cause the runs and tummy aches.
There are pellets for young bunnies and juniors.They need calories to help them grow into big,strong bunnies.
Fresh greens etc need to be washed and fed a little at a time.
Hope someone more knowledgeable with pass through here to advise more......
