    Alright, so I have had chickens for about 3 years now and finally decided to incubate some eggs. This is my first time. So I bought a brinsea mini advance. I have read and read and read some more. lol So my issue is I am at day 15. I am in Nova Scotia and the weather has seriously been playing havoc on my humidity. It is a constant battle. 30% (inside the house) one day, 55% another and so on, so my constant checking of the INSIDE of the bator has been ongoing. Mostly, from the first couple days it fluctuated between 25% up to 45% inside. However, yesterday and the day before, I had instances where it hit 60-65%. At this stage in the game, I don't want them to drown, so have removed all water inside. I am also concerned that their airsacks are too small.

    I know that this is totally a learning experience and the more I hatch the more I will learn. So far, all eggs have developed relatively to each other, the same. I have movements and all that. I am just wondering if over the next 3 days if there is a significant growth in the size of the airsack.. Day 18, is this Friday night.

    Just double checking... If Friday is day 18, that means day zero, the day you set them, is 2-2-15?

    Correct. They were set 2-2-15, at 9pm, so I will hit day 16 tonight.

    I think you're going to be okay. Keep this in mind... I remember reading a post that a RH of 20% can kill embryos, but I have not seen any properly documented studies to back that up. If I run one of my incubators dry the RH will drop to 10% regardless of what the RH in the house is. Guess what I'm just trying to say be careful, you're almost there and it would be a shame to lose them now. [​IMG]

    There's nothing wrong with those humidity levels. If you're worried about the 65% days putting water back into the egg and drowning the chicks, don't worry, that's not going to happen.

    Remember when you are dealing with humidity it is the average humidity over the period of the incubation that is going to make it or break it. 25-45 range is good. Flunctuations higher isn't going to effect them too much unless it's over a long period. Now, I would not recommend 60-65% as an average for the first 17 days, as I think you'd find that is too high. Good luck with the rest of the hatch!
