Oh wow that is really weird!! Maybe they weren’t being turned properly? Sounds like the chick maybe got stuck on one side? I know I had that problem with my turner when I hatched my first batch. I thought it was turning and theoretically it was (nothing was broken) but it wasn’t turning them enough.There was no movement visible when I candled the egg, I usually go off that too. It was just a dark band around the middle off the egg, clear at both sides of it.
The chick wasn’t underdeveloped, it was developed enough to be a day 17 chick which is what’s confused me as to why it was squashed into such a small part of the egg
These eggs were from posted eggs so some of the eggs will have been from the same bird but not all of them. Their air cells weren’t detached either.
All the eggs have been in the same incubator, temperature is running correct. It’s my first time using an upright incubator though, I usually use flat ones.
yeah I think if I ever get another incubator it would be upright. Although this last hatch I basically just left alone and I still had a lot hatch so idk. I did hand turn a few times early on though and move them around the bator so that probably helped haha but I don’t think that thing was even turning them because the quail eggs are soooo small that it just doesn’t push them when the rails move haha sometimes doesn’t even touch them 
plus I kept having spikes again but then again it was summer this time and last time was fall so the room was colder last time
