That's the link I'm most interested in too.
I just keep thinking Amino Acids and Proteins what part they play in the Domino Effect of sexual outcome or affecting its results. Probably sounds odd that I'd think of those, and I don't really know why that I'm even thinking of them in regard to this.
The only other thing I did this spring to summer with my birds feedings that was different was I fed them alot of Kril and Hermit Crab Food, I noticed the Araucanas loved the Kril the most. Probably had no bearing whatsoever on my hatch rates. I just remembered Kermit posting about it on egg color or the intensity of egg color and I also fed them Cranberries, which was another thing he posted about.
I'm weird about my birds food, I don't feed layer pellets at all, I feed GameBird Starter Crumbles, which is higher in protein than Turkey Starter, Scratch Grains (Corn & Wheat), and WildBird Seed Mix which has the Black Sunflower Seeds and I know you're going to find this hard to believe, maybe not, my eggs hatch in 17 days, under a Broody Araucana Hen and in the Incubator, I posted about it on the Araucana Forum one time and Kermit said its from the Quetros, and my start of Araucanas came from UCON birds which I've been told resemble the Quetros mostly and now is intermixed in my other Araucanas from them. The Same Araucana Hens also hatched out Large Fowl Marans eggs for me in the past, they hatched them out in 18 days. I only have 2 of those original Hens left and my one Rooster, and this year I'm going to put them together to keep more of them going. I also need to locate more Krill for the breeding season.
My friend in Florida has Sebastopol Geese, and she always feeds her Geese Mazuri Waterfowl Feed which smells like Fish, I had to lock my Bag of it up, my Cats wouldn't stay out of it, this past year she incubated 20 to 30 some Sebastopol Geese, some she had to cut out of the shells because the Membranes were like Leather and the goslings couldn't get out, out of all of the goslings she only hatched out 3 or 4 Ganders, so I don't know if the feed has any bearing or not, I'm just thinking it has to play a part somewhere down the line. The Health and Vigor of the Birds is definately effected by the Quality of Feed they are consuming, and its not cheap to feed that way. To alot of Hatcheries they wouldn't, they'd cull and hatch rather than invest alot of funds in special feeds and supplements, a Hatcherys Value Analysis is not the same as how we Value our birds. Most of us have all started out with Culls, and if you can find a breeder that would be willing to sell you a good quality Breeder Bird you're really going to pay for it, and you're definately going to invest in its care to pass on its genetic qualitys.
I'm definately interested in this link and think its worth exploring further.
What sort of Thermometers do you have in your Incubator? My Stepson took my Reptile Thermometer with the Probe, so I'm going to have to replace that before I start hatching again. I have the one on the outside and then 2 inside.
