Hatchright spray ????

Snake oils have been around for centuries.
Be careful.

I ordered it on Ebay and the enclosure says it is a mixture of herbs and vitamins. It comes in a plastic vial as a powder which you mix with water and spray on the eggs. I didn't notice any difference using it. In fact I thought that it made the eggs sticky and it was tough to determine if the eggs were leaking and bad or if it was just the dried on gummy spray mixed with the natural condensation of the incubator. I see that they are now selling it in large lots for $100 on Ebay, but it has no feedback score. So either its got a following by word of mouth or people are just buying it blindly, because I notice they had several orders for the lots of $100. A little goes a long way, so I can't see anyone ever using $100 worth, unless they had a huge commercial operation.

Mother nature has provided plenty that an egg needs to be viable. As long as your parent birds are conditioned right meaning healthy, there is no need for such products. This is my opinion only but, please dont waste your money on this junk, its a snake oil.

Has anybody analyzed the composition of the spray? Maybe it's just ascorbic acid, vitamin C. There were plenty of studies confirming this resulted in a significant increase in hatchability before. But new research indicates egg dipping vs spraying gives best results, and it has to be a certain percentage of AA on a certain day for a certain amount of time, all of which vary by species.

In layman's terms, AA dipping is an anti-stress treatment. You can read all the technical stuff about increased metabolism, oxygen exchange, free radicals, etc.

Hatch weight did not increase. Chick quality did.

The best for Leghorns may or may not be the same for other chickens, but I think it would be. If I read the paper right, the following procedure resulted in the highest (8.77%) increase in hatchability: On day 12 of incubation, dip in 15g. AA/L (I would assume the liter is sterilized water) solution for egg-zactly 3 minutes. No more, no less. 2 minutes worked almost as well, but why settle for less than the best chance of first grade chicks?

For Muscovy ducks, the best results (lowest mortality) were 20.0g/L on day 14. It says dipping in water for 2 minutes gave the worst results, so I guess the time was the same for both. Injecting 6mg. AA/egg worked best on day 20 for Pekin Ducks, but that study did not measure the effects of dipping. I wouldn't want to risk breaking the shell by injecting, so I'm going to try dipping on day 14 for my turkey eggs because they develop at about the same rate as ducks.
