Thankyou very much sir, that is great info to know.
I can picture it perfectly in my head from your decription.
I have some coturnix due to hatch on monday, I might try this with any unhatched eggs.
I think I knew about this already, but thought it was for testing eatin eggs that were out too long . . .
So the immersion in water wont hurt a unhatched chick, huh?
This is really good to know.
And "only keep the wigglers", that is the most straightforward answer I could ever ask for, thankyou.
I think on my last hatch of coturnix, I got so many in-egg deaths from too high humidity in the beginning, the set I have going now I have run lower humidity and hopefully will get better results.
So you give a full day before doing a float test . . . perfect
Do you the "wigglers" end up hatching well, or not so well?
In my quail hatching experiences so far, I have not really had any unhatched eggs hatch late; I have had a set that had 2 main hatches a few hours apart, but never any unhatched making it out days later.
I been giving my unhatched eggs at least 2 days extra.
