Float Testing, Checking Egg Viability For Late Or Overdue Hatching

[Vbrown71]

what type of movement do you look for ?

Youll only see movement if the chick happens to move right when youre looking. thats why it is not an accurate method for determining signs of life. This test was meant to be used with very rare, expensive, or fragile eggs to determine if they are indeed worth incubating.

What Don and many others have been trying to say for years now is...."PLEASE, Quit needlessly dunking your eggs in water!!" It will rarely give you any usable information. But it can be very detrimental to fragile chicks on the verge of hatching....

Many Folks Are Having Eggs Go Overdue For Hatch And Wondering If They Are Duds, Late, Or Have Had Some Sort Of Fetal Demise.... The Float Test Is Simple Yet Effect Way Of Checking Egg Viability.


I Normally Give Eggs A Full 24 Hrs Overdue Before Float Testing. It Works On All Bird Eggs- Period! Takes Very Little Equipment Or Time To Do And Is Easy To Perform.



Start With A Bowl Of Sufficient Depth To Allow The Eggs Your Testing To Float Freely Or Sink. Add 100 Degree Water To The Needed Level And Allow It To Settle( Quit Swirling And Calm Down)


Once Settled Take The Egg Or Eggs To Be Tested And Gently Lower Them Into The Water With As Little Disturbance As Possible. You May Need To Wait A Few Minutes For The Water To Settle Again After Adding Egg/ Eggs. Then Just Watch....


Eggs Are Judged By Observation With Results As Follows:


1. Sinker= Dud, Never Developed


2. High Floater (like A Fishing Bobber Without Weights) Say 45% Or More Of The Egg Above The Water Line= Dud, No Development Or Fetal Demise, Likely Rupture Of Internal Membranes Causing The Egg To Dehydrate.


3. Low Floater= Viable Egg, Development Full Term


4. Low Floater Rockin And Rollin! This Is The Live Embryo Moving Inside The Egg= Definate Viable Egg!


Once Test Results Complete Take Viable Eggs And Gently Pat Dry And Replace In Hatcher. Duds Are Best Discarded At This Time.



It Should Be Noted All Eggs Warrant Close Inspection Prior To Float Testing--- Any Pips In The Shell? Do Not Float Test! If The Shell Is Broken, Pipped Or Cracked In Any Way Water May Enter And Drown The Chick Inside


This Test Works Off Of Air Cell Development With Embryo Growth. Infertile Eggs Will Have An Underdeveloped Or Absent Air Cell That Isnt Large Enough To Float The Egg....thus The Sinkers.  Ruptured Membranes Will Allow The Egg To Dehydrate.... Thus The High Floater. Proper Development Of The Embryo Will Cause The Air Cell To Develope To The Point Where Viable Eggs Will Float With Approximately 10-15% Of The Egg Above The Water Line--- These Are The Viable Eggs. Obvious Movement Of The Egg Shows Signs Of Life For The Chick Within. Works On All Bird Eggs From Hummingbirds To Ostriches /img/smilies/smile.png

Can someone help me... I floated my eggs and based on the above I think at least six of them are viable but when I posted the pics and same comment on another forum someone said the the only thing the float test proves is that my egg that was moving is alive...

I am hoping someone can look at my pic and tell me if they meet the 10-15% test of viable eggs... Or if it's true that only the one moving is viable.

I can't say for sure, since this test isn't perfect, but in my experience it worked like candling: if the eggs look ok (and yours do) hang onto them. If they look really wrong, they're dead. When I did my float test, six looked like yours, and I saw minimal wiggling. One floated right to the surface on its side and was obviously a goner. The fresh egg I tested for comparison sank right to the bottom like it would if you were hard boiling.

I would keep your eggs in the 'bator and see what happens. They look ok to me.

Thanks for your response I appreciate it. I looked at my calendar and although I put them in on 229 the temperature was only 92 for the first 5 days until I could get it corrected so I'm thinking they might just be late bloomers because they're actually 5 days late we will see by tomorrow thank you so much

How did it go?

How did it go?

unfortunately they all died so sad.

We opened them up and took pics...they had feathers and everything... Just didn't make it.
