BackYardChicken is all that you say. But, it's a good resource and in the future may help you identify things like sexing. The best way to use it is to post photos, not just reading the advice. I'd love to see the responses you get for your Guatemalan mongrels. It's definitely not what they normally see. heh heh.

Any serious chicken raiser wouldn't scoff at your chickens. I expect their diet to be better than I can give ours! We feed them high quality organic feed, supplemented with scraps of greens and grasses. If they are lucky they get a few bugs. But, I expect your chickens get all the best free range feed you could hope for. More bugs and greens than our by far. I'd love to see photos of a cracked open egg when you finally get to the point (and get hens). I'm curious to see if the yoke is even more yellow than ours (a sign of high beta-Carotene content from greens) and if the eggs stand as tall as our do in a pan.

Anyways. Good luck with finding some hens and let us know if you see any tasty ways to cook old chickens down there. When ours stop laying in 2 or 3 years they will become food as well... even if they have names. :)
