Left vent open entire incubation period - dry hatching

[sccoastchicks]

This is only my second time hatching. I used the dry hatching method the first time around and had good results. The first time around the humidity stayed around 25-30% (this was during spring which is less humid for us). This time the humidity was 30-31% the whole time. Went into lockdown last night and I just realized the vent was fully open the entire time. Is there anything I should expect/watch out for?

Using an incubator, and maintaining certain humidity percentages is an improved way to increase hatching rates. BTW,,, most peeps agree, on the temperature,,,,, but the opinions on HUMIDITY (%) are not so closely accepted.
So that leads us back to,,,,,,,, Broody chickens do not use any added humidity, just what is in the air.
And I'm not posting this to start a debate, over Shrink wrapped chicks.
Wishing you a successful hatch.


WISHING YOU BEST,,,,,,,,,,,,,,,,,,,,and
