Sometimes laying on its side is a good think and can even look super dead, its called flopping which means they are very relaxed and feel safe. I hate it gives me a heart attack EVERY TIME! but my wife loves the bunnies so we have bunnies.

theres these things called salt cubes or salt licks that are good "treats". make sure you put up wires when you get home because they like to chew on phone chargers.

No problem glad to be able to help!

In the mean time try and get some timothy hay (any pet store should have it), lettuce (spring mix from any grocery store) can put that in a small bowl too, water (in a bowl is fine), pellets (use sparingly), dont over do on fruits/ use sparingly and they can be easily-ish potty trained, some normal bedding from any pet store and a normal litter box should do the trick. EDIT: Try and feed every 8 to 12 hours. any longer and they can get sick and with an already existing injury wanna make sure the fur bebe is taken care of.

If you have any questions feel free to ask.

if its an absolute emergency (the injury/ leg) VRCC MAY be able to do something depending on what you ask and how you ask AND theres a place up near DC thats 24/7. I dont remember the name, but im sure a quick google or me asking my wife can answer that if need be.

Wellesley is one of the only rabbit vets in the area (thats where we go to take ours) they may be able to help at least on its health and well being before you decide to turn it over to one of the animal control shelters or adopt out or whatever you choose.
