Can they be early?

[classroomducks]

Today is day 23 for my pekin ducks...I was candling with the last time with my students and talking about lockdown on wednesday. Upon candling, I was noticing that the air sacks seem really big...they have been fine up til now. But then I was noticing dark shadows in the airsacks that were moving...Could my babies be poking into the airsacks already? That would mean they are coming in the next day or so right? They are early then....?

and these things are moving...

The turner has been on...the humidity hasnt been up... what do i do? Lock down should be the 28...they are 5 days early...
