Quote:
If you consider that chickens have spent their ancestral life near the ground, it's no wonder they dont make time for cuddling, as you put it. Unlike arboreal birds, terrestrial ones have the constant threat of predation to contend with. And for the record, man at least represents a predatory threat to them.
Chickens as a species have only been closely bred for domestic purposes for a few centuries. They have been around for a lot longer, of course, and there have been attempts to tame them down through the millenia. The wide diversity in breeds, each part of the world developing it's own type, is evidence of that. In short, they are not the same birds as their wild jungle ancestors, which still exist in SE Asia. So, they have been changed.
And while there have been exceptions (the Egyptians, for example), breeding efforts have often been more about appearance or "gaminess," than food producing effectiveness.
The "need" for flocks of tame, egg laying, meat producing chickens was not really voiced until the middle 1800's and the onset of the Industrial Revolution. Prior to that, when agriculture was unmechanised, chickens were subordinate to more productive livestock and it was catch as catch can for them. Subsequently, the "wild" hasn't been flushed out of them yet.
I personlly doubt it ever will be.
