This is my newly hatched duck, we were totally unprepared for him to hatch today! He was the only one that hatched out of 2. He was born with a yolk sac I believe still attached. Also his feet are inverted! We don’t have a heat lamp so he is in the incubator! I mashed peas for him since we don’t have starter feed, I can’t get to the store until my bf gets back and hopefully that will be before 5:30 if not it will have to wait until 7:30 tomorrow morning. We have a damp towel that he is standing on so the sac stays moist. I’m really worried about that and his feet, any advice??
