i would put the hatchlings in a childrens plastic wading pool. then you can still keep them outside and not have the fish eat them. you can use a stump or rounded rock for basking and cover part with a tarp or the like for shade. the turtles should be eating now. try frozen bloodworms. they also make baby turtle food that is small enough for them to eat without biting. im not sure the name but reptimin broken up might work too. hope it helps.
