When to give up on eggs?

[bugglesmommy]

Out of the 6 eggs I had that were fertile, 1 hatched on day 22, the next hatched on day 23, but was seriously deformed, and the third hatched on day 24. It is now day 26 and the other eggs have not rocked, peeped, or indicated hatching at all. They were all alive before lockdown, but I'm wondering if I should call it on the last 3?

First candle the eggs and look for any movement - next open the eggs one by one - if the first one shows any signs of being alive, stop and give them a couple of days.

Great information - just read through the link.
I don't try to help (for the most part) I only open the eggs when I am 99% sure they have quit and died.

Great info! Unfortunately in the float test they ranked fully formed but did not move so I followed my gut and cracked the first which was dead. The second exploded when I cracked it and the third was also dead. What went wrong? 2/6 healthy, one deformed with a oversized bulbous head, twisted locked neck and twisted legs, 1 decayed and 2 formed but dead. This was my first hatch. Was it me or poor quality eggs?
