If I could only have one kind of chicken forever, it would be Delawares. They are just smart and friendly and healthy and very reliable layers. Two things: they peck at people's clothes (I've heard other people say this too) and they have a really hard molt once a year that makes them lose more feathers than the other hens: picture a pillow exploding. Sometimes there's a few days during their molt where they have difficulty walking -- they do a weird backwards walking thing. They get over it, though.
