Yeah, my advice would be to get a gravity gun (if it's in your pack), and scour the earth for a chicken. Once you have 1, you can set up an egg farm easily, and use those eggs to get more chickens, to get more eggs.
I also find that eggs are the best way of getting a chicken spawner, as killing a baby chick is counted the same as killing a full grown one, so load up with stacks of eggs, throw them into a pit, kill all chicks, repeat.
