Why were eggs delivered by the milkman? Why not the breadman?

Some products are delivered to consumers on a periodic schedule. At the beginning of the 20th century, perishable farm items such as milk, eggs and ice, were delivered weekly to customers by local farms.

When I was a small child in the mid-to late 60's, we had a separate "eggman," as well as a milkman and a breadman. However, I grew up in a suburb that was only slowly being converted from farmland to residential development, so that may have made a difference. By 1970, we bought eggs and bread at the supermarket, and only the milkman still delivered to our door. By 1974, we didn't even have a milkman any longer.

To answer the quesiton specifically, I'd say that dairymen or dairy employees, who provided milk, also had wives who raised chickens and who were happy to get a little extra money from the eggs. "Breadmen," on the other hand, were usually bakery workers, and bakeries didn't keep chickens on the premises.

Q. Are eggs considered to be a dairy product?
A. What part of the cow would you consider they come from?

Giving you the benefit of the doubt, we looked up the word dairy in a dictionary to find that it comes from an Old English word for a "female bread baker." The root of the word is the modern-day word for "dough." And it is conceivable to us that eggs have as much relevance to the origin of the word dairy as butter does.

But nowadays, the word dairy only has to do with milk and cream and related products: sour cream, butter, cheese, yogurt, etc. You may often find eggs and dairy categorized together (several Ochef directory pages lump them together, for example), but they remain as distinct as the species from which they come.

There were many different delivery companies, a few of which were: Adohr, Foremost, Challenge, Carnation, Royal Farms, and Rockview. Each company used a different style of truck and had their employees wear their own company uniform. The products sold by milkmen were mostly dairy products, but cakes and cookies were sold around the holidays. Some of these dairy products were: nonfat milk, skim milk, regular milk, extra rich milk, cottage cheese, butter, half and half, chocolate drink, orange drink, grape drink, fruit punch, eggs, sour cream, and bread. Of course, now, all of this can be easily bought at the local supermarket.
