Air Cell/ Humidity

[amynrichie]

I'm on day 14 of my very first hatch in my brand new Brinsea Eco 20. I candled on day 8 and 14. The air cell has grown by 1/8 - 1/4 inch, some eggs more than others. It is not as big as pictured in Hatching 101 article.

My humidity has been in the 30%-45% range. It briefly pops up to 50% when I first refill the one well, and I don't refill until it gets down to 30% or so. I've caught it once or twice below 20%. So the average should be in the range of 35%. I have not salt tested the hygrometer, but two hygrometers agreed within 1%.

Do I need to drop humidity until day 18- or do you think my air cell will be ok? Since this is my first hatch, I don't want to tinker overly much- since I have no experience- but am really unsure whether to make a change at this point.

Thanks for your input!

Overall they look decent to me for day 14. I use this chart. The hatching 101 page is the bomb, but for some reason this chart was easier for me to compare to:

I would say to continue using the humidity range you are using until day 18 Between 14 and 18 they should loose a good deal more.

This picture is more in line with what my eggs are doing. I will keep on keeping on, and see how it goes!
Thanks.

LOCK DOWN!

Some eggs have a really nice air cell at this point, and some haven't changed much at all. I started with 24 eggs, and tossed 14 clears at day 14. Of the remaining 10- all still had movement at day 14- minimal movement at day 18. I'm pretty excited about the progress!

My guess is that I have a fertility issue. I have a cochin roo trying to cover 15 hens. I forgot to crack open the clears to be sure. I'll post a couple pictures of the current air cells.

The brown looks good, but white air cell hasn't changed much since day 14.

The last hatch I did I got eggs from my sister's flock. She has somewhere around 100 birds. Out of the almost 3 dozen, I think 13 were clears. I called her and told her at least one of her hens weren't getting the love she thought they were. lol

on the ones in lockdown!!

The brown looks good, but white air cell never has changed much.

Ya, the brown looks real good. The white ones may have thicker, less porous shells. Hopefully they will be fine.
