One of my chicks hatched on day 21 but the other seven haven't even pipped the shell yet. It is now day 22. I'm told that I can't open the incubator before the eggs hatch (which can take up to day 25) because it will lower the humidity. I'm using a still air incubator (Brinsea Octagon 10). I'm concerned that the chick who hatched on time might starve to death before the others hatch though. What do I do in this situation?
