How much should your four week old rabbit eat?

A four week old rabbit may be just starting to wean, maybe nibbling a bit at pellets and hay, but also still drinking milk from its mother. By six weeks or so, the bunny may be fully weaned. Until the bunny is about 7 months old, don't worry about portion sizes: just give unlimited access to hay, water, and pellets. If you think your bunny isn't thriving (isn't eating or growing), bring him or her to a vet who has experience with baby bunnies. See the related questions below for details.
