Chilled hatching eggs?

[lazy gardener]

I know I've seen information somewhere, but can't lay my hand on it. How cold can a hatching egg get before being collected, and still have a good chance of hatching?

28.4 seems to be the temperature under which a hatching egg can't drop or they will be damaged. From what they say, eggs can be close to freezing for quiet awhile and still be OK.
Brinsea has a nice article on hatching eggs / embryos and what effects temperature has on them.

Good link there Kelsie. Im doing my own experment (unintentionally). I have been collecting hatching egg since Feb. 10th and on occasion have found frozen eggs that were layed later in the day and did not get picked in time. Been so very cold here plus I started a lot earlier this year. My first hatch is now 9 days in the inci so I will candle soon to see whats developing. I suspect the cold may have an effect on the fertility also as it does on egg production too.

Thank you so much Kelsie. I'm hoping that the weather moderates a bit during collection week for my hatch. I'ts been below 0 every morning this week, and barely makes it up to 20, before plunging back down again. I'm so very done with winter.

I had two frozen eggs that I put in my incubator on a whim and low and behold one has been developing. My hens hadn't been laying much, so I'd come across a frozen solid egg that hadn't cracked yet and toss it in. Last candling was day 17 and now I'm on day 20 waiting for some hatching.
