my last duck hatch they all died fully formed.. Now I candled my Black east indie eggs at 2 weeks or 2 1/2 and about 10 were dark and forming.... I candled them for the last time tonight (lockdown in 2 days) and only 2 are Black w/ the air cell!!! all the others have a black ring around the egg next to the edge of the air cell and clear on both ends. one looked scrambled and one looked half formed. What am I doing wrong?? This is so dissapointing I was looking forward to my BEI!!! im not even gonna hold my breath for the other two eggs to hatch... Heres what the ring looks like.. I guess that means its dead right? I highly doubt a duck is fitting in that black spot.. any advice on exact humidity for trying to hatch the last two?
