This is our first time hatching eggs. Our hen was sitting on 7 eggs. 3 has hatched at day 19 and day 21. Now at day 23 this is what the eggs looked like. I never candled these eggs until now. So im not sure what im looking at. Not sure if a chick is in them or not. If so don't think they are alive. I haven't seen my hen sitting on them in two days. Can you help explain what I'm looking at?
