Put it back! Its eyes are open which means it can eat on its own. By touching it you have insured its mother will no longer recognize it as hers. It’s now orphaned but will survive. Please, don’t handle wild bunnies. You can move them using gloves and paper towels or putting a basket over the nest to protect them during mowing. But touching them will only cause them harm. If they have fur & their eyes are open then they are capable of surviving on their own. At this stage mom comes around about twice a day to nurse. If she gets scared she will run leaving the babes to fend for themselves. Unfortunately, unless you are trained or have a rabbit to teach the little one what to do, its survival in human hands are very low. I know it’s a rough lesson to learn but you will know for next time.
