I have 9 cyuga duck eggs in my incubator all formed embryos Sunday was my lock down date on day 24 of incubation. I got ansy last night since there's no signs of hatching no peeps coming from inside no cracks no nothing so I candled them last night to see if any internal piping was taking place... Anyway I forgot to turn the incubator back on! This morning the temp had dropped to 68!!!! Did this kill the babies!??
