Eggs under a broody muscovy question

[aworldintime]

Ok so I am new to broody lol.
My muscovy from what I had guessed started sitting on her eggs aug 22nd. So we are past 35 days. I candled one today and saw movement but the air sac seemed a bit high still. She is well over my count of days incubated. Will they ever pip lol? The weather is getting colder to. I am worried they wont make it.

I've not hatched many duck eggs, but I did find with chicken egg hatches, even under broody hens, sometimes the hatch goes a day or three over the "due" date. I had a hen hatch a chick on day 25 once! 3-4 days after the rest of the clutch. So long as there are signs of life in the eggs, there is hope

There is life. I candled 1 egg. I am so worried and excited hahaha. It is getting way past hatching day.
