Huhhhhhhhhhhhhhhhhhhhhhhh!

I'm gonna do my best, I think it's: "Just got 14 of this breed. Any tips? I have two of the same (breed) that I think should start laying soon."

I think you nailed it.

Unless there is some genetic link between Large eggs and Roosters I would think that the size of the egg would not have any influence except on egg size of the hatched babies. I under stand that there are people breeding for individual taste in chickens , is there some kind of movement toward a larger chicken and a larger egg ?It seems that my plate is quite full being a newbie. What genetics control egg size and how are they linked to other genes? such as tail length , Like wise how is color affected by egg size ? is there any relationship between between darker eggs and size and lighter eggs and size. what known variables exist in Mar rands and Americana's besides color of the hen and rooster and the color the eggs will be produced. ?

When I incubate eggs, the temps are between 98 - 100 deg. I usually hatch more girls than boys. I recently incubated bantam cuckoo mar an eggs. Temp on top of eggs was 102 deg steady. Out of 12 eggs, I hatched 10 definate cockerals and 2 pullets. I had them until they were 5 months old. I actually had 1 hen and 11 roosters. How did this happen? It's kind of too weird to be a coincidence. I purchased ten more eggs from same person this time temp 100. 3 Roos and 7 hens? The farmers hen to rooster rashio is 1 male to two hens. What do you guys think.

although science says only some birds are capable...

I too believe this is the case w/ my Faverolles. There is a definite link between incubation temp and sex with many reptile eggs...and chicken are not too far off from lizards

I think temperature does NOT change the predetermined sex of the chick in the egg. Chromosomes do.

That said, under less than ideal incubation techniques, you will hatch more males as they are tougher.

All embryos gonads start in the same place. In humans, the testes are in the abdomen like the ovaries. When the fetus is at a certain age, they drop down if a male, and stay up there if it's a female. Thus, making the embryo unsexible until it's of age. In some cases, ( in humans ) the testes don't drop and the body's produces pure estrogen, making the apearence feminine. It takes a doctor to see if it's a male or female. Now back to chicks. males have higher body heat because of the testosterone. By increasing the temp in the incubator, I caused the chicks to change sex prenatle. Thus, causing the excess males, that's just my theory. With you theory, I would have lost eggs because the females would have died. I had 100 percent hatch rate.

I have no real studied knowledge, but I can say that I have had all kinds of variations in incubating. My BW rooster, Dorian, fathers more females than males - around 70% are females. I bought eggs off a woman and I hatched 100% males from her one Cochin rooster - so did she. I believe the father plays a part just like in humans because of my experiances.

Technically the female determines the gender of the chicks. But this is an interesting puzzle!
