Hen walks to her eggs and sitting on them!
 

Does she know that the eggs require that to hatch and get chicks!!

How does she know??

She probably read a book on it.


Or it could be that hens who sit on their eggs tend to hatch a lot more eggs, so they are more likely to have offspring with the same trait than hens that don't sit on their eggs, and eventually that trait spread far enough into the population to become common.


But I'm going with the book idea.

?????????

Da Gawd o the Gaps tole her ta doit! :rock:

Well, she obviously read The Big Hen Handbook by Henrietta Cluckensquawker.

Which came first, the chicken or the egg on your face?

Where are you getting confused? I'll try to help you understand it.

I suspect there may be a few fundamentals of Evolution that ahoba might not quite grasp.

Jesus told her in the sermon on the coop. Dont look it up, it's not in the bible.
Not everything Jesus did made it into the book.

A lot of academics these days think Jesus spent a lot of time feeding the chickens, some even think "the twelve" may have been chickens.

You said that 'hens who sit on their eggs tend to hatch a lot more eggs'

How they know that the eggs need incubation to hatch and before how they know that eggs will hach?


Regards,

How much do you know about evolution, natural selection etc?

I doubt that the hens "know" that an eggs needs incubation. It's likely an instinct that some were born with to cover their eggs for protection etc. This had the bonus effect of incubating the eggs, and so the eggs that were inclined to hatch quicker/better when insulated did so in a more efficient manner, meaning that more chickens were born with those traits. Because there were more of them born than chickens without those traits, they eventually came to be common in the species.

I suspect this also. In which case let's go all the way back to the beginning with some handy dandy links -

Ahoba, I am going to give you the benefit of the doubt for the moment, and assume you are an honest person who is actually seeking knowledge. The answer to your question can be found in a basic study of Evolution. I will try to give you a simplified answer.

The answer to your question lies in the behavior of the predecessors of modern chickens and the consequences of their behavior over long periods of time. Birds / dinosaurs which protected their eggs and babies, had a better chance of producing offspring that lived to reproduce. As the predecessors of modern chickens gradually evolved from poikilotherms to homeotherms, the preconditions for an egg to hatch also changed with the changing organism. Potential mother chickens that did not take care of their eggs properly would simply not have any offspring that lived. Chickens that did take care of their eggs, would have offspring, and pass the traits for nurturing to their offspring.

Does that answer your question? :)

I can summary your answer to be one word “INSTINCT”. Without “instinct” hen will not sit on her eggs. Am I right?

ghoulslime, I am seeking a correct knowledge for sure. I hope you do so.
