i just candled an egg ive been incubating. barely any pores and its real clear s i can see right through to the yolk. its been about 3 days theyve been going! i candled it and seen this big black rounded mass. itd maybe the size of a quarter or a bit bigger even. almost like a ring cause its lighter in the middle but not to light. how do i know if its alive? it seems to have gotten bigger since yesterday since i overheated them and candled them to see if they were ok!
