Day 21 Nothing Going On

just wait.. All you can do, really.. If your temps swing alot, they could be developing slower and could hatch later on.. Also you have to raise the humidity to near 70% on day 18 to allow the chicks moisture/humidity to form a barrier between themselves and the shell. This allows them to break free from the shell and not "stick" to it and die. That may be a problem as well.. If you have done everything right so far, don't worry still.. Ive heard people hatching eggs on day 27!! a full 6 days AFTER their normal incubation period.. I would just wait and see what happens.. Dont open your bator till the end of day 23 and then re-candle if you cannot see life moving around in them, toss them, or just sit and wait until the end of day 25. re-candle, if anything is alive, give it another day, if not, toss the batch and start over.. Remember consistent temperatures are very important to the development of chicks. With temp swings of 4 degrees, you are really limiting your potential results.. just my 2 cents..

 

I know nothing about incubators, but with my Bio-Bators, I have hatch days go a full week past hatch day and still had 100% hatch. Good luck.

 

Since you said your temps varied from 98 to 102 in a still air bator, give your hatch a little more time. You can recandle today if there are no pips to check for movement. You might want to fill up the water anyway so that would be a good time to do it. Just don't lolly gag around.

 

Na... you're doing fine... There are some people (not me) that spritz their eggs when they remove the lid.
