Mom should have blood on her backside, and I doubt that she has rejected her kid due to his feet. It looks like he has contracted tendons, and they will correct themselves in a week or so with use. You can splint them, but it will still take a week or so for them to straighten out. Contracted tendons are usually due to a lack of space in the uterus. Not sure what to tell you about the not bagged up part. She either has milk or she doesn't and that is not really negotiable. Stand the baby up and stand over him facing the same direction. Place 2 fingers on either side of his tummy in front of his hipbones. Does his tummy feel full? If so, he has nursed and you can pen him with his mother and just keep an eye on them. If not, get your flashlight and check to see if you can see blood on anyone's backside. If so, you've found the little one's mother. Restrain her and try to milk her to see if she any milk. If so, hold the little guy up to her udder and try to get him to nurse. If she has no milk and the baby has not nursed, you will have to bottle him with colostrum. He has to have colostrum - it is critical!
