How fast does an adult rabbit completally digests food

[NolanPad84]

My rabbit, Bob is going to be 5 yrs old this September. A few hours ago I gave her a surprise treat with parsley & bits of carrots. Soon enough she was dumping her pallet poop normally. Fast forward to now she wont touch her hay. I dont know if she's still full after consuming a little more parsley than usual. So my question is how long does a rabbit feel "full" before being hungry again?

It is starting to worry me a bit. Thanks in advanced

They should never be full. Rabbits should be eating for the majority of the day, How long has it been she as ate anything?
