Thanks again for the infoThe conflicting information continues.... It is important to seperate facts from opinions.
Humidity once you have a pip must be greater than 65% however Metzer farms (the gurus of duck egg hatching) recommend a wet bulb humidity of 94 degrees which calculates to a relative humidity of 80%. Cornell University states the same.
If you have several chicks hatching, the humidity will increase to 95-100%. This is because the chicks are wet and drying. This wont hurt your birds and the humidity will dissipate through your open vents.
Now for opinion
The term lockdown was invented to stop people over-assisting a hatch. Opening the incubator to check progress every 4-6 hours is a little different but once I get the first pip I rarely open for 24 hours. This is not because its detrimental, but because its not necessary. Getting in there are "helping" is a different story. I dont assist hatch until 36 hours from initial pip. Typically delayed hatch chicks are the ones that have leg issues, die in the brooder or are forever the runts. I will assist to evaluate viability only. The chick has to push its own way out. i do not have time or patience for special needs chicks and they get culled.
Shrink wrapping is a factor of low reltive humidity over a long period. An incubator at 65% RH will shrink wrap slow pip to zip stage chicks a lot faster than an incubator set at 80% humidity.
