Don't crack the eggs. They will either hatch or they won't. If by day 25 they have not hatched you want to move them outside and just bury them. If there is rot in any of the eggs you don't want to smell it. Believe me!!!!!
Hang in there! If most of us had a nickel for everytime we made this exact same post or saw it everyone at BYC would have a nickel. I predict in the next 24 hours you will edit this post to read *UPDATE I've got pips!
I am on day 22 with no signs of life as well....very frustrating! I have 34 eggs in there. The last week before lockdown they did not get turned because my fiance accidentally unplugged it to plug something else in and I didnt realize it until lockdown day
So...I will give it until day 25 as well, and I think just bury them like the post above if nothing happens. THEN...start over.
