Float Test Live Eggs? Interesting Video

[aart]

I think that is only done in very late incubation(over 23 or so days)to see if egg is viable/alive.

I have heard of float testing PRE INCUBATION

This makes way less sense than late.

Not something I would personally do but then again I also only candle eggs once during incubation

We too, only candle one time. Even if the questionable eggs are left in our incubators, they keep the other eggs in place and help prevent too much roll over.
Candle once, remove the duds and go with the flow..
I don't plan on doing any float test, pre incubation or pre hatch.. Bloom is put on the egg for an important reason.
Thanks for contributing to the thread!

That is exactly what I was researching, "what happens to the bloom, if you float test?" How much washes off?
I have heard of float testing PRE INCUBATION, but to see it that late in the development stage just knocked my socks off.
I am an extreme humidity conscience hatcher. I use aux meters and tweak to optimum non dangerous levels since we had that catastrophic batch a few months, contributing to major umbilical probs and leg splays in half the hatch.
I never want to see such a site again. Now I see a video of emersed in water eggs that are wiggling.
Brain overload....

In answer to your original research reason -- many folks here routinely wash eggs before incubation with no ill effects. I had some pretty nasty eggs, so I washed them, mainly as an experiment. They still hatched. I washed eggs from under a broody after one got broken. They still hatched. My theory is that its more about the process as a whole, not just one thing that causes something bad to happen. Obviously there are single things that can ruin a hatch -- high temps, for one, but washing the bloom may or may not ruin a hatch, it depends on other factors.

My whole attitude about incubating changed when my broodies taught me a lot of lessons.

This is the video I saw first, prior to the late into incubation video(subject of this thread).

This particular video got me searching for answers about the effects of the bloom washing off during the float test process. This is a video series this fella posted. In his incubation storage process, he sprays the eggs and saturates them with a 50/50 mixture of Listerine and H2O. Then floats them.
We personally don't wash, clean, wipe or do anything to breach the bloom barrier. We kinda hand select eggs and inspect for cracks, defects, size and shape. It it has poo or dirt, it gets washed and put into the breakfast pile.

So many people have so many preferred methods, I prefer to use our rule of thumb. Very comfortable keeping it simple and not complex.
Thank you aart for your time.

@pyxis
this was my morning rant!
Start at square one..

Has anyone tried this using a sandwich baggie, or some thin plastic to keep the water from actually touching the shell?

This is an older thread, but that's an interesting thought. I have float tested before but it was after day 23. And the eggs were only in the water for a max of 10 seconds, but that was enough to see movement, or not. And the only one that wiggled is the only one that went on to hatch. People don't like this method, but I've found it illuminating in certain situations.
But in a sandwich bag, keeping the water away from the shell is a good idea.

I would think the air inside the bag would make the egg float, and defeat the intended purpose of seeing what the egg does in the water. But it could be worth some experimenting.
