After trying to get some genetic answers recently I decided this is the best way to find the answer .
OK here is some info worth knowing on fertility after removing a rooster . I just candled last weeks eggs '. Lots of clears . So I checked which pen produced them 1 for all other pens . The pen that had the white rooster I removed 19 clears and 14 fertile . A weeks gather . I think this went to day 10 after the rooster was gone . Shows how fast fertility drops . This is why I save for a week ( usually ) then put in a new rooster and start saving on day 14 . I removed the rooster mid week . Slow getting it done .
Well for best results no more than 1 day past due date . You can go longer but there will be some losses . The temp seems to dehydrate them . I have put them in chick boxes and kept them as a experiment . Better survival . I did this when I shipped chicks to see how they fared at home versus the shipped ones .
The problem with water in the incubator is you will drive the humidity up. Do you have any place else you can put them? Do you mean chicks chirping or eggs chirping?
If you have eggs chirping today, you should be ok if they hatch tomorrow. IMHO.
I do too. once they start hatching they will keep the level up on their own, Use something with a small mouth or throat so it does not get too high..
Good luck. My hatch in on Friday when I am at the NPIP school.
Good luck and have fun wherever you are going.. and don't forget the poultry powder!
What is NWTF??? I bet powdering them was fun! Good luck..
