Hey guys! Newbie incubator Mom here, and this is my first set of duck eggs to hatch. So far I’m seeing very obvious differences in my eggs and on day 7 I noticed 4 were questionable so I waited to candle again today at day 10 (just in case there were slow developers?) well today I removed 2 eggs and there’s one I’m stumped on. It’s dark but not like the ones developing well and there’s some vein spots in there, and the yolk doesn’t move- but there’s an obvious difference in the development. I’m not sure if this was one that tried but did not succeed and I should take it out or if it’s just developing differently?
If there’s anyone who could help, I’m attaching a picture. Thank you guys!
