Could these eggs hatch on day 28?

post #1 of 4
Thread Starter 
I have two eggs remaining in my incubator that passed the float test but are dark shelled so I am unable to see any internal pipping. The egg is clearly full of a full size chick and the air sac looks as you would expect at full-term. Our first hatch was two chicks on day 23 late in the day with our second hatching on day 24. What is the latest these two could hatch? Do I intervene?

:welcome  The late hatching indicates that your thermometer may have been reading incorrectly.  It is possible, but not probable that the remaining eggs are still viable.

How long should I wait? I don't want to toss an egg that has a slight chance of hatching.

Have you done the float test?  Viable eggs floated in warm water should show some movement.  Type 'float test' in the search bar at the top of the page - information should appear.
