The worst thing about the staggered hatches is keeping the hatcher clean...bleh!
Yeah it's a little hassle but not a huge one, I simply candle the remaining eggs the day after a hatch and put them in small plastic baskets after I candle them... I place these small baskets on a sheet of foam and then drop the lid of the foam incubator over them while I clean the bottom of the real incubator...
I did just built a forced air hatch box last night though, more so, so the daughters could more easily watch the hatching then for cleaning... Making sure it holds temps right now before I switch over some eggs due tomorrow...
