This is my thrird time using my incubator. 1st time was quail, 2nd time was 24 chickens (3 clear eggs and 2 DOA). So lockdown will begin for me tomorrow evening. I have 24 brown eggs in the bator, 3 of which seem to be clear. I'll double check the three I've marked as possible clears, and pull them if they indeed are non performers. I've heard of folks cutting down egg cartons and setting eggs in them for the final lockdown period. Please explain this, and if you have photos, that would be great. Any reasoning as why this is done would also be helpful. I can always just set them in the bator on their sides after I remove the turner, but if there is a benefit to setting them in a carton, I'd be open to try that as well. Many thanks!
