I would drill both ends and fill the damage with crack resin until about 1/8 inch from each side of whatever rock chip started the crack. Then after curing the filled-in crack and mini bullseye/drill holes I would fill the rock chip with whatever resin is appropriate for it using an injector. If the rock chip is a bridge crack or small bullseye the capillary action of filling in the crack might be sufficient to fill it too without using an injector on it, but if it's a star-break I recommend the above process to avoid star-break legs being left un-filled. Also to make sure too much air isn't pulled into the injector while filling the star-break it might be necessary to put a little resin and some curing tabs over the parts of it that turned into the crack (the 1/8 inch parts left un-filled as mentioned above), before pulling a vacuum, to create a good seal.
