What should I do with an injured, wild baby rabbit?

Ok this is very serious im a animal LOVER ok so what you should do is take it to a vet see what they say if the vet dosent take it in and you care for the animal help it by going on the internet find a heat blanket the right food care ect.... see if the leg is healable maybe even check with the vet see if you actually CAN take care of it till it recovers if its not possible let it out on its own DONT take it outside by your house belive it or not after humans touch the rabbit the momma will smell it and kill or abbandon the rabbit
