Ok... so today is day 20 in my first hatch. I started with 10 eggs, when candling I noticed 3 were not developing so I took them out. 5 were regular sized eggs and all doing well and at lock down were all still alive. 1 really large egg Im suspecting twins, but i cant be sure the egg is dark. 1 is not much larger than a regular egg and Im pretty sure it has two embroys (i attached a video of my candling at day 11) I have not checked anyone since. I did check 3 times a day. Im not sure what I should do with the 2 double embryo eggs....
My impression is it’s just the head and the butt you are seeing, since they are kinda curled inside the egg.
