How often does a week old bunny eat?

First answer: You should not have a two week old rabbit away from its mother. If this is not possible, just put put a bowl of rabbit food once each morning. It will eat this throughout the day. Also, see a veterinarian if you are unsure of what to feed it.

Disagreement: A two-week old domestic rabbit can't really eat solid food yet. Pet rabbits wean at about 6 weeks. At two or three weeks, you can put out hay, pellets, and water, but the rabbit still needs formula (kitten formula, KMR): 7-13 cc/ml each feeding (two feedings daily) -- that's according to the HRS FAQ link below.

Wild rabbits are different from domestic rabbits. You have to know what species of rabbit you have, because this will change how you raise it (including diet: what, when, and how much).
