I'd have to rewatch the entire season to be sure, but I just assumed that the search for Sophia took at least a week, maybe as long as 2 weeks.
I was going to say that Carl's recovery was coming along if it had only been a couple days. I think it was longer than a couple days.
What I'm sure everyone else is wondering, is will Herschel's chicken population now start to recover since Zombies are no longer eating them?
Why do zombies eat? Chicken or other animals, especially?
On one hand, I've heard they bite to spread their disease.
That's why the half-body zombie (bicycle girl) in the first episode wants to bite Rick. She has no stomach to digest food with!
If animals can't get the disease (that we know of) - what's the point in eating Rick's horse (first episode)?
OK - dogs bite and eat anyway. So if a dog or higher predator, like a zoo tiger got bit, and it attacked and ate people, it wouldn't be shocking. Right?
Now here's an idea: if an herbovore like Rick's horse got the disease and started attacking and biting people - that'd be freaky! A carniverous horse! How about a mass of hamsters from a pet store that attack in swarms? Or cows chasing and eating people?
Maybe an animal gets bit but the zombie is killed or interrupted, and the animal survives, gets the disease (or a mutated strand), and starts attacking?!
I do think the zombies bite to eat, but it's not driven by a hunger that can be satisfied. In other words, no matter how much they eat, they are always going to want to eat more. In fact, the drive to eat is probably so all-consuming (no pun intended) that it overrides all other brain activity... or... all other brain activity is dead except for the instinct to eat. However you want to look at it.
It has to be something about living flesh, otherwise the zombies would just eat each other. Maybe it's something about warm blood and once the organism dies and the blood cools, then it is no longer desirable to them.
Yeah. Zombies are weird. They're just not normal people like everyone else.
Obvious? Well Herschel doesn't get it.
If you look at zombies as having a severe brain disease, then everything makes sense. You can't really assign logic to the actions of an insane person, and I think that would work with zombies as well.
