How early can call ducks hatch

[sabrinaTmartens]

Hi everyone,

I currently have 4 call duck eggs in my incubator ( started with 10 but some not fertilized and others only blood ring). They are now on day 21. Yesterday i candled and noticed i hardly saw any clear area's left only the dark mass of the ducks. After candling i noticed 2 of the eggs rocking and wiggling a few times. Could these be signs off a early hatch? Can call ducks hatch at around 23 days? If so i'll stop candling and raise humidity tonight.

I've never incubated calls, but others have said they often hatch closer to 25 days instead of the 28 of most other breeds. So yes, they're probably getting close to hatch.
