Good luck with getting some chickens! For information on raising chickens, I would check out BYC's informative Learning Center:

You may also want to read up on chicken coop designs (
Coop Designs), and breeds (
Chicken Breeds - BackYard Chickens Community). When getting chickens, the more research you do beforehand, the better off your birds will be.
Yes, Silkies certainly wouldn't be a good choice if you want eggs, though they sure are cute! I would recommend dual purpose breeds, like the Wyandotte, Australorp, Orpington, Easter Egger, Sex-link, Plymouth Rock, Jersey Giant, Sussex, and Rhode Island Red. Dual-purpose breeds are generally docile, tame easily, are hardy in various types of weather, and lay colored eggs (brown, greenish, etc.).
If you want lots of eggs, then you could also try some of the Mediterranean breeds, including the Leghorn, Minorca, and Andalusian. Those breeds are egg laying powerhouses, but tend to be flighty and not make great pets. All Mediterranean breeds lay white eggs.
Or, if all you want are some ornamental, pretty birds, you could go with a wide variety of bantams and standard sized chickens. Common bantam breeds include Silkie, Japanese, Old English Game, Sebright, Rosecomb, and Wyandotte. Bantams won't usually lay many eggs (and the eggs will be small), but they are adorable little birds and are delightful to have running around the yard.
Unfortunately, all roosters are capable of crowing, and will crow at some point in their life. Some are quieter than others, but I've never heard of a truly "quiet" rooster. Fortunately, hens are nearly as fun as roosters, and don't need a rooster to lay eggs or be happy.

Good luck with any future chickens!
