Exactly. If I really had to, I'd consider stopping on day 12. But I wouldn't be happy about it.
Thanks to all you experienced hatchers chiming in on this!
Fight the Fallacies!
I understand you shouldn't spread false information but no turn egg isn't a total fallacy. I'm not recommending the practice myself, but its interesting that egg will hatch when not turned. In a study I read using coturnix quail eggs the hatch rate for turned was 77% and 65% for not turned . 12% is a significant difference, but people will lead you to believe you can't hatch any if not turned, and that's a fallacy.
But is there an equivalent test for chickens as there was for quail?
I'm sorry but this just seems lazy, and this is coming from a lazy person.
I remember reading a couple scientific studies done on hatching chicken eggs in regards to turning. I remember that not turning did not have a good out come especially when not done the first week and that it effected both the chicks ability to hatch and decreased the size of blood vessel network (scientific name I cant think of now but its the vessels we see when candle).
All I know is I spent $60 for those eggs and it was pure devastation. Never, ever again.
It's entirely possible that for whatever reason quail handle it much better than chickens, but I can say without a doubt it is not a good idea for chickens. My humidity and temperature were on point throughout that incubation, and it took me weeks to figure out just how the **** all but four of those eggs expired.
Here is a link to poultry science articles that deal with turning during incubation. https://academic.oup.com/ps/search-..._SiteID=5340&SearchSourceType=1&allJournals=1
There are studies using chicken egg. As a rule they fair far worse than the quail. Appears the first week in crucial. I have achieved around 50% but I wasn't using control eggs to compare to. Again I'm not recommending it, it's just something i'm interested in.
And yet a fair number will hatch healthy and I find that curious.
