gryeyes, you are just the best! Your posts are always on point and so informative.
Mrsfoote, alot of peeps choose to lightly mark one side of the eggs with a pencil (just an X or small defining mark), to be able to keep track of placement. If you are not using an auto-turner, then you are most likely to just have the eggs laying on their sides. If this is the case, mark one side and just gently (and slowly) turn the egg so that the X is either face up or face down. It is recommended that eggs be turned a minimum of twice a day, but ideally more like 3 or 4 times. Do take care to not be too quick, as the air sac could become dislodged or the contents of the egg could shift and separate.
What kind of incubator are you using?
Edited in case you want to do the auto-turner:
The auto-turner has more than one purpose, depending upon who you talk to. Aside from turning the eggs for you (really tilting them from side to side instead of rotating around), this will also hold them in the fat-end-up position. Some folks swear that this helps the development of the air sac and assists the chick in hatching. That said, many more will argue that the eggs lay every which way in a nest, so the position has little impact. An auto turner will often turn the eggs every hour (very slowly in constant motion), so the uniformity seems ideal to many.
ALSO, you may also want to read up on the use of pulp cartons during lockdown/hatching. Many people love using these, cutting them down to 1/2-1/3 of the sides. They hold the eggs in the same upright (fat end up) position, which could help the chicks via orientation, but also giving them a bit of "traction" when they are pushing through the shell. (The idea being that they are wasting energy scooting the eggs around the incubator floor.) Some folks can't stand them or have had bad experiences, though. Definitely something to look into and make your own conclusions about!
