Hi Phage

Thanks for posting. I had seen this 'plate' from a posting on genetics that GaryDean did earlier in this thread - and have found it not only fascinating, but my star-to-steer-by for my "standards" for my chickens. HOWEVER, I had never see it in color....which is amazing. Thanks for posting the color version.

ETA - my newly hatched males all match 5 and of my newly hatched females 3 match the number 3 pattern and one matches the 4.

thanks the field is huge it would be impossible for them to destroy it, the field could fit 100+ in

Hi Steen,

Nope...the chick gender is determined at the time the egg is fertilized....... GaryDean26 can set me straight if I'm wrong---but those chromosomes come from Mrs. Hen.

ETA - here is a very informative link. http://kippenjungle.nl/basisEN.htm#berkenEN

Here's an interesting but odd article on how the chomosomes work....I was looking for a simple sentence beccause the above article is overkill lol

2X - I hadn't seen it in color either. This is very helpfull.

Thanks!

Good to know... I wonder if the Mrs hen has something in her that takes into account the year shes having. Humidity , available food, or the amount of roos or pullets around her Like gary dean was pondering. But when you think about it, from slugs to humans and everything in between I think fish are the only thing that can decide there sex. everything else is just random right . after all if there was a way to get mostly females everyone would already know by now right.

Yep! In chickens the gender is determined by the hen and is set at the time the egg is laid.

In the case of the 18 eggs that produced 7 cockerels and 1 pullet there may have been 9 eggs that would have produced pullets and 9 eggs that would have produced cockerels, but the conditions such that male embryos were better suited for survival to hatch.

I have heard of some people that wanted to hatch fertile eggs sold for consumption that had been refrigerated. They were advised that they could do so, but the hatch rate would likely be low and probably result in a lot of cockerels because the male embryos were "stronger". I don't know if anyone ever did any test hatches to prove this though. It is probably just a theory, but along the same lines as the humidy theory.

actually they are finding that gender in sea turtle eggs is determined in part by the temperature of the nest -- several of my envt'l studies students have done research on these, it being a concern re: climate change that warmer and warmer nests will produce only one gender (female, i think, as it gets warmer).

so, not "deciding" gender, but being dependent on external factors, not just the chromosomes...

reptiles too now that i think about it. haha. maybe I'm all wrong. we might still be able to find chickens life factors that might help persuade a wanted sex. maybe its just mammal's that are random... Its weird that there is allot species belonging to the sea have other factors determining gender.
