I am currently on my first ever hatch. Today is day 17, my sister is over so I was showing her the babies inside. I set all of my eggs at the same time, but on inspection tonight my Ayam Cemanis and Deathlayers look perfect, but all three of the Bielefelders have huge air cells, the air cells appear to have a huge dip, and when I was moving them, it looked like there may be some type of liquid inside the cells? The air cells are cool to the touch, which I guess would be normal, but I have never read anything saying as much. Can anyone advise on what may be going on here? I didn't look for movement cause I was slightly panicked that I may have done something wrong, but the entirety of the egg was dark aside from the air cell.
