It's really not a big deal.

I've only had eggs "stick" to sterilites every now and then. Nothing sticks to the Iric CB-70's because they are coated with some type of oil I'm told??? They work great!

Even when they "stick" you can just take your time and slowly remove them. I had to take some bad eggs out of the incubator this morning that were "stuck" to good eggs and you just have to be patient and work them out carefully ... same thing if they "stick" to your box.
