For overall great birds, Buff Orpingtons. They lay well (I've got some 5 year olds still laying a couple eggs a week), will set and hatch chicks, but don't spend all their time on setting, either. They are very pretty birds- not spectacularly pretty like the Silver Laced Wyandottes or some of the other decorative breeds, but feminine and a very pretty golden color.
I do like the SL Wyandottes, and have 5 each of those pullets and the Buff Orps in this year's order.
I've always wanted to get some Partridge Rocks, and finally ordered some this year. Straight run- and got 4 roosters and a single pullet :-(.
Silver Spangled Hamburgs are also very, very pretty birds- but flaky and flighty. I never did like the Rhode Island Reds or Hampshire Reds- just personal preference, I think. They go through a really ugly gawky stage while growing that seems to last forever. But I did have some Rhode Island Red bantams, and those hens (apparently the "old fashioned" type) were very pretty birds- deep bodied and graceful.
I also really liked my Black Australorp hens ("black" really doesn't describe them, especially the roosters- in the sun they're green and purple iridescent!), but the roosters were very aggressive and nasty. And nothing I did changed that. I now have 4 Dark Cornish roosters which are 4 and 5 years old, and they are very polite and well mannered. A couple of them tried attacking me in the very beginning- and one good "lesson" solved it permanently.
The prettiest hen I have is a cross between a Dark Cornish rooster and a Silver Laced Wyandotte hen. Sort of a golden laced color and absolutely gorgeous.
If you ever want to really have fun with breeding chickens, try a few Araucana BANTAMS. The full size ones can be pretty, too, but I've been disappointed in the last few I've gotten from Murray McMurray. It seems they are infusing laying hen blood to improve egg laying rates, and they have all looked alike- like Brown Leghorns. But the bantams are all sorts of colors, and the chicks they hatch are as well. I have two cockerels right now who are "red, white and blue"- seriously! Red bodies, cream-white hackles, and blue tail feathers. Really neat.
