I think if what your breeder said was true, everyone would be refrigerating before setting eggs(I know I would). I don't know, it would be interesting to know if anyone else has heard this or if anyone has hatched out any roosters that were refrigerated.

If it were true, then hatcheries would refrigerate eggs to get more pullets.

None of the methods work, except a better chance of selecting for hens that lay eggs that have female embryos(Hens determine gender in chickens. An embryo is either a male or female based on what she provides--different from humans). Even then, A hen will usually have both male and female embryos--It is really just statistics.

Agreed i need to know! LOL ive had some bad luck with fridge eggs. Ive set a total of 24 in the past with different days in the fridge and ive only had one hatch

Storage for refrigerated eggs is supposed to be small end up. I have seen a study where cold storage increased hatch rate for eggs over two weeks old. Up until then it did not make a difference.

Then the other 24 were roosters?  lol

I'll let you know after the HAL since I refrigerated all of my eggs before hand.

Hahaha ikr?? Ok let me know! I think this would definately be a cool thing to research!

My last hatch where all fridge eggs, I set 19 and 9 hatched... A bunch from my old hens eggs where infertile, one ringed out two got shrink wrapped at hatch.

What gender were they??

Looks like 5 male 3 female 1 idk...

Aaah ok! All good stuff to know! Then i wonder why i had so many clear fridge eggs....

They might have been stored big end up?

They might have been stored big end up?

I stored mine big end up because I thought you where supposed too... Oops next time maybe I'll get a better hatch rate by storing them the other way....

I Seriously dont remember....i took pictures of them and put them on instagram after i had candled and put the air cell up....but im not sure if you remember or not me posting about alot of the small air cells and the saddle cells....man this is weird haha

I thought the same way!

Wait, they're supposed to be stored big end down??? I thought the big end was supposed to be up!!! Well, there goes my hatch rate.

I found this very interesting webpage:

AnnaUneven temperatures in incubators

Does egg location in the incubator affect a chick's time of hatch and hatchability? In still air incubators, you'll find relatively wide temperature variations throughout the incubator, but even our top of the line Brinsea Octagon 20 Advance Incubator shows differences in hatch rate related to egg location in the tray. The picture to the right is the summary of my results from two hatches, suggesting that eggs in the center are less likely to hatch than those around the edges, and my notes show that central eggs also tend to hatch later.

The fan in our incubator keeps air moving, so you would think that all of the eggs would be equally warm. However, a reader on our homesteading blog suggested that radiant heat from the central heating element preferentially warms the eggs directly underneath. His hypothesis makes a lot of sense, as does his solution of using some kind of barrier like aluminum foil below the heating unit to block the radiant heat while allowing the fans to continue to circulate warmed air. It looks like I'm going to have to do some experiments with moving thermometers around inside the incubator to find out whether there really are high temperature pockets and how to fix them.

I'm not knocking the Brinsea, but I did find the article interesting since I have experienced something similar with my RCOM.
