When I put the eggs in, I originally just had a bunch of Showgirl eggs. The next day, a friend pulled me two eggs out from under one of her broodies and I put it in. Both of those eggs are significantly further along, development-wise, than the Showgirls. They're at that point that it's almost completely dark in the egg, all I can really see is some veining along one edge, and the air cell. The others are still in that "rocking and rolling chick in the egg" phase and I can see more when candling them. It's Day 16 now. I know I am approaching lockdown- what do I need to do to prepare for that? I do that on Day 18, correct? Remove the egg turner, add as much water as the channels will hold, along with a sponge? This is my first hatch, and with the LG still air it has not been easy. I killed 15 of my eggs, but if I can just get one Showgirl and one of my friends buff Silkie eggs to hatch, I will be sooo happy.
