EDUCATIONAL INCUBATION & HATCHING CHAT THREAD, w/ Sally Sunshine Shipped Eggs

[BantyChooks]

Banti - this experiment is about fruit fly eggs, not chicken eggs. I don't think the results apply.

Fruit fly!? I must have copied the wrong link, sorry.

No, you copied the right link - the folks in that thread didn't read the article carefully enough. I also posted on the thread.

Oh, thanks. Thought I was going batty. Where's the stuff we had in the notes on this? I know we've had discussions before....

Not sure. Gosh, I hope no one put that in the educational stuff for BYC - Sumi (as staff member) posted on there thanking the OP for finding the article. (I don't get it - it says very clearly that it's fruit fly eggs - why didn't anyone notice that?)

What I wish to know is why they x-rayed fruit fly eggs to figure this out. Really, fruit flies?? Maybe there's something else in there that explains it?

Wait what!

Congrats super cute!

Congrats!! what breed?

Sorry for the super late reply. My house has exploded with activity and I'm just now recovering....

I am an expert in fruit fly eggs!!


I hatched some once in Biology 121, I think it was.. I could not really figure out what color their eyes were..

So I might have used data that was in line with what I was suppose to find,,,and written my paper and conclusions off that...

I have felt guilty over this for 40 years..Thanks for allowing me to confess my sin so I can sleep well tonight...


Now what about this post:

I have a question possibly with more than one part. I have been hatching for a few years and I run staggered hatches with 2 incubators.

Of course, we know about the bullseye indicating fertility (blastoderm phase whatever). We also know that shipping screws up air cells.

So I paid lots for eggs and my octagons are super reliable. When the eggs arrive at the post office (app on my phone), I pick them up, take them home (not to sit in the car). I immediately unpack, label, circle air cells, make notes, weigh and set into an egg carton while waiting 12 to 24 hours to set them. Depending on air cells, I decide when I will turn. I know what humidity I start with, my temps are stable and I have a spot check to confirm.

Now, by about 4 days of incubation, I can pass a good light over and see red veins on developing eggs. I don't make any determination at this time, and I don't actually remove the eggs. Day 7, I officially candle, Mark air cells and weigh. On day 10-15, I pull clears, depending on if I need the space.

I usually crack them, and locate the spot. There is almost always a clear confirmation that this egg has only the very tiny spot... no bullseye or further development. im not discussing quitters, here.

I was told that this current order of eggs may have been x-rayed and therefore would have no bullseye. This makes no sense to me. Certainly I can understand it being the cause of a quitter, but it would not reverse the bullseye stage that indicates this is a fertilized egg.

Personally I have to wonder why you candle so much...BUT then I wonder why all these people candle so much weigh eggs and all the OCD stuff they do... I chicken never candles her eggs, never weighs them and they hatch...I try to be just like a chicken when I incubate....





X-rays would not remove anything you could see with your naked eye from an egg, I don't think....

Is it possible someone sold you bad eggs,,,or did the boys at the post Office have a rousing game of volleyball with your eggs? Both are possible..

How much is a lot of money spent for eggs to be mailed to you? I have some eggs I could send you.....

I really think you are searching too deeply for an easy answer....... The eggs did not hatch, they were shipped, so that takes from the chance of a hatch....Where they disinfected? Infection and dirty eggs take from the chances of a good hatch...

Heat and cold take from the chances of a good hatch...... So many variables, blaming the Xray machine seems a little far fetched... Even though I mark all eggs I shp with a "do not xray" label, I doubt very much the postal employees pay much attention to the label..Other than to know it is a good box to play ball with....

The article has absolutely nothing to do with the eggs or trying to hatch them, per se, it is a study done at Columbia University, by their Institute for Cancer Research in the 1920s. They were trying to figure out a way to test and measure X-ray doses for the purposes of their biologic effect, and were seeing if fruit fly eggs would fit the bill.

"But it is possible to find biological materials which will serve as a convenient dosimeter, within a proscribed range of intensity and wave-length. Each material will have its own limitations, for each differs from the others in its reparative powers, in the nature of its protective envelopes, and in its type of variability. I have used the eggs of the fruit fly, Drosophila, as a dosimeter, and have found..."

Looks like someone read the title of the article, looked at a picture or two, and made up the rest and posted it on BYC as proof that chicken eggs weren't affected by X-rays in shipping. You'd be amazed at how often that happens - I've seen it where someone will reference an article as proof of something, and when you do your due diligence and pull the article, you will see that it actually says the opposite and someone just looked at the title only (astonishing behavior for a scientific professional). @Phage - do you want to weigh in here? It's kinda sorta closer to what you do...

"SUMMARY

1. The eggs of the fruit fly, Drosophila, can be used as a dosimeter for estimating X-ray dosage. Within limits which are discussed, there is a correlation between dosage and effect.

2. Because a large proportion of the eggs is normally resistant to X-rays, the lethal dose must have a sufficient intensity to kill every individual in a short time. This is probably true also for those tumor cells which show the same type of variation in sensitiveness to radiations. "
