There appears to be a tried pip on upper right. There are various cracks around as you see so I'm not sure what's going on. When candled it looks like what is the unsuccessful pip is just below the air cell line. (The air cell is at an angle). I know assisting is the last resort so I'm wondering if this little guy needs help. I have six hatched on day 20 and 21 and six still in incubator on day 24. I float tested a couple last night and they are still viable. But noticed all the "cracks" in this one so didn't float.
