My incubator air temp is between 99.8 to 100.5 with a fan. and the same probe placed on an egg read 98 is this okay or should the egg read over or just about 99.7.
Air temp is NOT egg temp and can be very misleading in a small bator. Normally the air temp will be higher than the egg temp. If you are using a remote probe thermo, good for you! Now find one of those squeezy, water-filled tube toys and put the probe in there. Then, put THAT in the bator. The water filled toy simulates an actual egg and will give a true egg temp reading.

Dont pay $12 for one, either. Go to
WalMart or the Dollar Store and get one for a buck. If you can't find a squeezy toy, then partly fill a sealable plastic baggie with water and roll it around the probe, secured with rubber bands. That'll do in a pinch.
This is day 4 of setting and it is 100 outside. Can I move the bator outside open the lid and candle instead of dropping the temp. if done inside.
No need for all that. Just open the lid, candle and close it back up. Dont dawdle, mind you, but dont worry about it.
However, candling before day 8 is a worry. The delicate tracery of veins that is the developing, early-stage embryo is VERY vulnerable to mis-handling. It's best if you wait until day 8-10. Besides there isnt much to see before then, anyway.
The incubation cycle is actually made up of 4 separate phases - -
Phase 1: Day 0-7.
Early development. Germ begins development once temps reach 70 degrees. There is more proportional growth during this phase than in later phases. It is also most vulnerable now. Best to leave it alone during this time. Only gentle turning is advised.
Phase 2: Day 8-14.
Embryo is more developed and wil begin to create its own body heat. Heart will start beating during this phase.
Phase 3: Day 15-17.
The embryo becomes a chick by this time. It is regulating its own body temp and respiration really steps up. You'll note a temp spike in the bator in the beginning of this stage because of this.
The chick begins movement towards the air cell in preparation of hatching.
Phase 4: Day 18-21.
The chick moves to the air cell and takes its first breaths there. Stop turning now, so as not to disorient the chick. It is fully formed and is little dependent on temps, by this stage. The final preparations for hatching are completed and hatch out begins on day 21.
