Refrigerated eggs experiment complete!

[Minky]

Ok, so about a month ago I was asking if using high temperatures to hatch out eggs would produce more females (because it would basically kill the male eggs).
The discussion led to many responses, and one that came up was from a member who says they only hatch out refrigerated eggs, and they do this to get more females, less males. So, having an abundance of eggs I thought I would try it. I set 21 eggs. Almost all started to develop... (candling is hard with dark and blue eggs) but in the end, I only had one chick hatch...so maybe not something I will try again. LOL. However, it is a very robust little chick. I am looking for better names then its current one... "FRIDGE"
I will let you know if it turns out female.

Ah what a cutie pie!!! Bummer the others didn't hatch but at least you ended up with one!

I like non-conventional names so I like your name but here's some other ideas: Frosty, Chill, Chilly, Elsa, Alaska, Snow, Polar, Blizzard, Jack (jack frost), Frio (cold in spanish)

Congratulations on your little sweetie!
I incubated 6 eggs last year that had been refrigerated for over 3 weeks, one hatched and was female, though I doubt this is scientific by any means.
How about Zero?

I love Chilly!

So, having an abundance of eggs I thought I would try it. I set 21 eggs.

What was age of eggs and how long in fridge?

I've read the best temperature for storing eggs is 5-10 C and never to store them in fridges as humidity is too low.

My Fridge stays at 7 degrees C and 70% Humidity. To me it seems perfect for storing eggs.

So is the conclusion out of this that storing in a fridge will reduce 21 eggs to only hatch 1 or that possibly the incubator temperature was not set right?

Or is there another scientific reason why 7 degrees C and 70% humidity would be so disastrous that I cannot comprehend?

I too want to know if you know exactly how your bator runs.
Calibrated thermometers?
Salt tested humidity gauge?
Age of eggs?
How long in fridge?

I've hatched fridge eggs (quail) before and almost all hatched but I run a tight ship with my bator.

So you hatched these chicks from the fridge? Iv wonted to try this, Iv seen that the store bought eggs we have are firtail

good to know kiki, cause honestly most care guides mention not to store in a fridge but I am suspecting there is more to it like that americans maybe call freezers fridges just like rugby is called football and motorways are highways even if they aren't high?
To me cold is anything that isn't warm wheras I have had many conflicting discussion because of this as in America there is a clear distinction between cool and cold. so my cold might be someone else cool and they are interpreting what I am saying in a different way.

I think for this experiemnt - ie kill any embrionic males before incubating - the fridge temperature would need to be set to 3 degrees. Something below 5 degrees but above freezing.

Considering all 21 started developing I think this experiment was not performed correctly.

It is very interestin though, are fridges set above 5 degrees safe to use and will the 3 degree test work and how long does it need to be for the males to be affected but not the females
