how long till eggs are dudds

[Casey207908]

I am on day 23 of incubating. 5 hatched within 24-hours of each other on day 20-21. Now nothing for 2 days. How long should i wait to shut the incubator off and throw away unhatched eggs?

Usually day 24 is the longest I'll wait, or 48 hours after the first one hatches

I'd candle them or do the water test to see whats going on inside.

I waited until day 25 and cracked them open. All 3 eggs had fully developed chickens, fully feathered and all? Any ideas what could have gone wrong?

what was your humidity during incubation and lockdown?

 

[Casey207908]

45-50% during incubation. lockdown 65% My havabotor says 45-55% during incubation and 55-65% during lockdown. I definitely stayed within those levels. I don't know what happened, especialy considering there were 3 that didn't hatch.

Well my chicks just finished hatching been almost 5 days since the last one ( I have 4 ) so I had a plan to take out 1 a day so as not to upset the hen sitting on them if they were all gone. Candled it I knew it had something in it but I didn't see it moving and couldn't hear it.... but when I cracked it open it was still alive It was going to die so I had to put it to rest I didn't want it to suffer, poor thing I feel so bad.

I dont like it that high during incubation. I never have good hatch rates. I go about 20-30% during incubation then 60-70% during lockdown.

That stinks.....I am wondering if i should have left them in longer. All the chicks that were unhatched were definitely dead when i broke the shell.

Really....that low during incubation? What kind of incubator do you have, or does it matter? I would think following the instructions from the manufacturer would produce good results..but maybe not?
