came across 4 newborns this morning beside the mailbox, less than a foot from the road, at the time I put up a barrier so they could not crawl onto the road, checked this afternoon and momma has not been back, they are barely cleaned up after birth and they were covered in red ants and cold to the touch, they have been brought in and cleaned up, put in a box then fed milk replacer with a eyedropper....what else can i do
