Todays the end of day 20 and I’m worried. Neither of my 3 eggs have pipped yet, and earlier I took one out (only one because I didn’t want to touch the others) and candled it. There’s lots of veins and the dark mass (chick) however the air cell looks untouched, what does this mean? Do you think it just hasn’t gotten to it yet? If you’d like I can take it out Again and take a photo, I’m worried they’ve died.
