Ok so this might be a strange question, but my eggs were put on lockdown today and are expected to hatch on the 28th or 29th. I turned off the auto-turner and put each egg in a different section in the bator. Well each time I check the incubator the eggs are in different places. There is no way anything can bump them so why do they keep rolling around? This is my first hatch so I have no idea about any of this stuff. Is this normal? What does it mean?
