I don't know much about hatching from an incubator (only hatched birds and chicks naturally) but I do know that stressing him out will do the most harm the fastest. Be sure he is warm(no drafts) and quiet. Don't handle him unless you absolutely have to. The egg sack can feed him for quite a while, maybe two days. Do a search on this site for conformation on that. Do you have any pics to give us an idea of the amount of blood loss? I think Beet juice is supposed to help with low iron so perhaps you could put some in a dropper tomorrow and give it on his beak a drop at a time, that way you won't have to worry about it going into his lungs. Maybe someone with more knowledge will come on and confirm or deny about the beet juice. I know you want to help right away and it seems urgent to do something immediately but I think wait and see how things progress might be best right now. I am so sorry you are going Thur this and I pray it will work out.
