Hatchright spray ????

Now..... if it actually does what he claims and increases "Fertility" wouldn't it have to have something "unmentionable" in it?

I'm guessing that formulation costs extra.

But if what it really turns out to be is a hatching egg sanitizer... which is what his description does actually sound like as to how it works... then the eggs might seem as if more of them were fertile, because some of the early die off/failure to develop may well be due to the bacteria counts. It's an inexact use of language

Did you look at the bacteria counts in those papers? Those articles are from universities. The first one is from the extension service at North Carolina State University, the other one is from UC Davis.

The NCSU pub said that after 14 days of storage, hatching egg bacteria counts went from 154,000+ bacteria per egg to over 310,000 bacteria per egg. They documented that when eggs were properly sanitized as soon as possible after collection, the number of bacteria colonies went from 121,000+ per egg (on the control eggs), down to 331 colonies per egg. That reduction in bacteria apparently greatly reduces microbial infiltration of the egg.

I bet the bacteria are more of a problem in incubator eggs than in hen-hatched eggs, because the darned incubator creates a certain amount of condensation, which helps the bacteria penetrate the shell. Sweating is bad.

The UC Davis article has very clear, nicely written instructions and a variety of options.

Given that I had a several quitters last summer, and no eggs that made it to pipping, I'm thinking I will look into this further.

Still looking for (and into) sanitizer question.

Here's an interesting article which focuses more on the angle of bacteria which pose hazards to humans, such as salmonella. It sounds like hydrogen peroxide in an appropriate strength may work...

The most interesting thing to me was about the perpetuation of salmonella through eggs and hatching, based on exposure of the eggs to salmonella. It's not just a result of poultry feed... apparently the chicks can be hatched with salmonella and spread it to other chicks...

Here's an abstract of an article about quaternary ammonium sanitizer, which says it increased the hatch rate...

This one has interesting comparisons of the effectiveness of quaternary ammonium, hydrogen peroxide, phenol and plain water:

Okay, I have been looking and looking for something like this... a description of various poultry disinfectant product lines:

Here's one that explains how to make a disinfecting solution:

Here's a long, old thread from the chicken people... everything I am turning up seems to concur with/support the statements that BlackSheepCardigans made

This is a helpful article that mentions which products reduced the hatching rate:

Okay, I started disinfecting the eggs with hydrogen peroxide, because I already had a bottle in the cabinet. So far, I have treated 5 eggs with 3% hydrogen peroxide (various concentrations have been studied, from 0.7% up to 6%, with eggs still hatching even at 6%). Only two of the treated eggs have enough time incubating so far to candle, both of them are showing very vigorous development.

Who knows? Got another 3 weeks to go

Not sure what to try next... waffling between chlorine & quats
