I spoke to Sam, my egg man a while ago and he has sixty+ laying hens right now. He has a dozen Orphington/Barred Rock crosses that lay the most, red-brown eggs. Eight Leghorns that lay white eggs, 15 Araucanas that lay the aqua eggs and 8 Americaunas that lay blue-green eggs and about 10 Araucana/Orphington crosses that lay either buff-speckled or pink eggs, sometimes a hen will produce both colors - three of these crosses lay the buff eggs with red speckles, very pretty. He recently got some Wyandotte hens that are just now reaching egg-laying age. They are almost as large as the Orphigtons.
These all produce an egg a day and often the Orphintons will produce an egg every 15 to 18 hours - he calls them his egg "machines" but all his layers are free range, as are the guineas. He has both the Buff Orps. and the Blacks. Mature they can weigh up to ten pounds.
He has several other chicken breeds but they are not all reliable layers and as he is building his flock, he sets those under a broody hen. Some of the fancy chickens are broody but don't lay well (silkies, for instance). I've seen some of the fancies and they really don't resemble "normal" chickens. He trades with other breeders and has a rooster that is extremely colorful. It hatched from an egg that was supposed to be from an African jungle fowl that was shipped from a breeder in Florida. He has not yet turned it in with the hens.
Sam called me a while ago and said he has counted all his chickens. He has in total 183 of which 44 are pullets and the others are fancy "show" chickens that are kept separate from the others, except for some of the older ones that are his "broodies."
He also has fifteen guinea fowl, too many ducks to count, 5 geese, and in his game bird houses 50 pheasants, and 200 quail, 100 partridge, plus a few other odd ones and two peafowl who have the run of the farm and which, along with the geese, are the "watchfowl" as they give a loud warning whenever any strange animal or human appears.
All his chicken runs are completely enclosed with wire mesh because there are coyotes around and also hawks that prey on loose birds.
