Would love everyone's advice. This is my first hatch. First 5 were great, #6 not so great. He hatched in the middle of the night. 90% of his feathers are matted. He yolk sac (I assume) was dried to him. I got him out, moistens the yolk sac to where it can fall off, but he's so gummed. He won't open his eyes. They open, but he doesn't open them. I wiped him down with warm water and returned to brooder but I'm so worried about him. I know I need to keep him warm. But I'm terrified. I don't know what to do and I don't want him to die. I have one other who has a couple sticky spots but they aren't anything to worry about. His eyes are open, he's active, totally normal. What is your advice??
