What breed? Are they 28 days? That one egg in the video looks good, like it will internally pip any day now. Duck eggs take a long time!! Don’t loose hope.Woke up to no change...my 2nd viable isn’t moving or having any air sac drawback either.
Were these shipped eggs?Tossed a quitter. Down to 3. One trying to internally pip for 4 days now...1 fully developed but not seeing movement & one underdeveloped with a saddle shaped air sac. *sigh* so much for starting with 12 this time...
Yes. Same state. Going to order some more and try again.
Ok, shipping can make a big difference. Sometimes during transit there can be damage done on a cellular level that you can’t see but will affect hatching. I was going to say that this year all of my duck eggs were very late. And it’s not correlated to my temps because I’m also hatching my chicken eggs in the same incubators at the same temps and the chicken eggs are hatching early. But all my batches of ducks were late. I even gave some to someone else, locally, to hatch and her hatch was late too. So don’t give up hope on these guys.
Hens go broody when you don’t want them to… and won’t go broody when you do.
