I still do not know how many eggs you have set, but,,,,,,,,,,
yes move all the egg into the hatching tray,, take them out of the egg holders and just lay them on their sides..
I have also done it like the guy told you he did it, but once in awhile a chick will get lost or stuck on it's way down..although, I have never had one die..
very critical.......
do not open the bator again for 3 days.. the chicks will be fine..
keep your humidity at 60% or there abouts..
watch your temperature closely..
that is all you can do..
If you cannot resist the urge to open the bator,go to a movie. get out of the house for 3 days........ duct tape yourself to a chair...
