Actually I would suggest starting over, but trying to nurse those back to life at the same time. If they don't do well you will have started off a little sooner than waiting to see if they were going to recover. Put the plants in the shade and keep them out of direct sun and wind for a few days. Start your new batch and as soon as they are emerged set them in light/dappled shade when you put them out. As long as it isn't dropping into the 40's at night time and the critters can't get into them I would leave them outside day and night. Just give them shelter from wind, rain and direct sun. It won't hurt them to have some wind/sun on them though. Just try to keep it minimal while they are little.
