what kind of medium is that? My main concern is that the container that the eggs are in, there is to many and to big of holes. You need a good amount of humidity in the container for the eggs, having so many/large holes can effect that. Some people on the forum don't put any holes in there container and just check it once or twice a month for gas exchange. I hope this helps you.
For my eggs i prepared a small container for my eggs and moved them into a larger container 3 days after they were laid. So if you are careful i think it would be okay. nothing is developed yet.
