I am no expert by any means, only hatched once before using my same set up. The previous hatch, as well as his one were from shipped eggs. On the previous eggs, had a lot of detached air cells but most of the chucked grew until the end. Unfortunately I had 8 die at the end I believe when I took them out of the carton and laid them down on their side to hatch. They were fully formed etc. I had 10 out of 30 make it on that hatch. Would have been 18/30.
This hatch I started with 32 eggs. 14 clears, 1 blood ring, and 1 exploded egg. I'm down to 16 viable eggs which show great movement every time I candle, and yes, I have candled on day 10, 11, 13, 14, and 16. Day 17 for me now. I left two eggs in the carton on my prior hatch and they hatched without any problems. I am thinking of doing the same thing on this hatch but we'll see how it goes. The air cells on the remaining 16 eggs look real good. I may play it by ear so to speak.
Anyone else leave their eggs in a carton or turner in an upright position to hatch? I use a standard cardboard? carton, not styrofoam.
These pics were from before I removed the clears, blood ring one and exploded egg.
