I eggtopsyed my last 3 eggs today on day 24 ( I took them out last night, the incubator was starting to smell & I wasn't sure if it was the eggs or something else). Anyway, all 3 of them were fully developed but had not piped internally, 2 had small amounts of yolk left to absorb & the 3rd had a little more yolk. I did not see any movement when I candled them last night before I took them out. Not sure what happened, maybe temp changes got them when I took all the other hatched chicks out.
