Wow! Your boys could teach mine a thing or two.Tossed 2 clears from the 30 eggs in the MaticoopX.
No blood rings so everything else went into lockdown. I candle on day 18 for clears and usually blood rings are obvious enough to see. Everything else stays. I don't check for movement or anything like that.
I was surprised out of 42 eggs only 3 were clear. I collected some like a day or two after setting up the pens. Good job boys.
