Is it Possible to have " too much" Humidity? (INCUBATION)

[Lazy Farmer]

View media item 7893753I never read the model #'s on the boxes before today.
I quoted 9200 several times..
My bad everyone!

I edited the tag keyword from 9200 to 9300.
I will edit earlier posts with explanation a little bit later

What is a roll over?

If the question is in regards to my comment, I was talking about when hatchers roll over eggs that have been pipped so the pip is not face up. I mark my air cells on days 7/14/18 so I know where the chicks should pip. When I go into "lockdown" (which for me is a joke) I place my eggs so where they should pip is face up so I can see them when they do. It also helps me to have an idea when they pip so if they hit 24 hours of non progression, I start an assist.

All my air sacks are at the top of the large part of the egg since this how i placed them into the turner. Please explain Pip.
Today is day 14.

If your humidity is where it needs to be (which is VERY important as to whether the chicks hatch come hatch time) the air cell will grow as the moisture evaporates through the shell during the incubation period. Generally the air cell will grow more on one side. This side where it dips the lowest is generally where a correctly positioned chick will pip.
There are two stages of pips a chick makes. The first pip is unseen to hatchers (unless they candle at this point) because it is when the chick pierces the membrane under the air cell to allow them to get their beak up in the aircell. This is called an internal pip. Generally within 24 hours from this point of progression you will see the external pip, usually when hatchers mention a pip, this is what they are talking about, when the chick breaks the shell. Often it is just a bump pushed up in the cracked shell. After this pip it can take anywhere from a few hours to 24+ before they progress to zipping, which is when they actually zip around the egg and push out. During this time between pip and zip the chick is resting, strengthening lungs and the vascular system between egg and chick is shutting down. Also if a chick hasn't finished absorbing yolk before the pip, it will in most cases finish during this time. A lot happens between pip and zip and this is why assists should not be done hastily.

I had 4 roll over fatalities in latest batch. Today is day 22. I have assisted six eggs with unzipping and removed the outer membrane and stopped with the inner membranes because total blood absorption did not occurred yet. One is ready to push out of the inner sack any minute now but the second still has more absorption left. I have assisted 6 on this last batch today, not yesterday. 4 are dried and hanging ten with the early Hatchers. 2 to go. Only 4 eggs out of 35 did not peep.
I did good taming the humidity the last couple of days. No help from the LG 9300 meter that always reads 23% no matter what conditions are present.
(Edited my wording.. I'm exhausted and confusing myself)

Awesome info

Day 14
Im very close on this chart Ive been at about 47% for over a week. My bator is almost dry.It runs at about 38% dry in my closet.I will run 2 days dry and candle some more.
I can adjust my humidity with in a few points with the channel system.
Since most of the information here says 65% to 70% for hatch I plan on setting my hatcher at 65%

I just ran last batch almost dry until lockdown and ran 70 to 75%

I run dry if it's about 25-30% at least. If it's not I add a wet spong. I don't ever put water in my wells the first 17 days.
