Seriously, It's starting to get to me. Why do chickens constantly lay eggs even without a roo around. Obviously the trait has been bred into them, but even without the breeding, they must have laid a fair bit in 'the wild' (if chickens every truely were wild). What crazy kind of evolutionary quirk would have them popping out infertile eggs? Why go to all that time and effort if the end result is just going to be a tasty meal for a passing predator?? Or is egglaying really 100% people induced? It might be a stupid question but its bugging me and I want to know..
