What food do you have her on now? Is it alfalfa based? How much does she get and how much does she weight? There's not really anything a shelter could do for the kits unless they just happen to have a nursing doe with new kits or kits ready to be weaned, that they could foster to. Hand feeding can be done but is really the least advisable option due to the aspiration risks involved. If she hasn't fed them by morning, your best bet is to hold them up to her belly to try and nurse. Best way is to sit her on your lap and hold onto her, then have someone else bring the babies up from underneath to nurse. But you may not even need to worry. As long as she has milk coming in, she should get to the point where she will want to nurse them to relieve the pressure from the milk.
