Its day 22 and one of my 3 remaining eggs have hatched (yesterday). One of the eggs has a thin crack about an inch long. My silkies are still happy to sit on it, but I candled them today for fun and didn't see anything. Both are 1/3 dark and 2/3 light. I don't know if this matters but the one with the crack is dark green and the other is a white smaller egg that looks like its a bantam. What should I do? I really want these to hatch. I know I'm not supposed to do this but should I open them? I can provide pictures if it would be helpful.
