Ever Wonder Why Eggs Are Shaped Like Eggs? Scientists Say They've Figured It Out
NDTV ^ | 23 Jun 2017 | Ben Guarino

But the universe of wild bird eggs is far weirder and more diverse than the oval products on the supermarket shelf. Hummingbirds lay eggs shaped like Tic Tac mints - "perfect little ellipses," per ornithologist and evolutionary biologist Mary Stoddard. Sandpiper eggs come to peaks, in the manner of teardrops. Owls plop out tight spheres not unlike ping-pong balls ... scientists linked egg shapes to birds' flight behavior. Stronger fliers, such as swallows, had elongated or pointy eggs. Birds that couldn't fly so far or fast had rounder, more symmetric ones... Aristotle, said Douglas G.D. Russell, curator of the egg and nest collections at London's Natural History Museum, "believed the cock hatched from a pointed chicken egg and hens from the rounder." The analysis revealed adaptations for an aerodynamic body had a "knock-on effect" for egg shape, Stoddard said. Pointy or elongated eggs don't help a gravid bird fly, in other words. But the demands of powerful flight restructured internal organs. The abdominal cavity of the superior fliers became smaller, for example, forcing egg shape to change

I question your answer. It works out to one egg per chicken per day, six eggs per day from six chickens, seven days at six eggs per day is 42.

I question your answer.

Not eggxactly my answer.

There many answers are out there, also many variations of the problem.

As usual, check twice and show your work.

Start with 1.5 hens laying 1,5 eggs in 1.5 days. How many eggs do 1.5 hens lay in 1.5 days.

1.5/1.5 = x/1 |cross multiply
1.5x=1.5 so x = 1

1.5 hens lay 1 egg per day. How many eggs does 1 hen lay per day?

1.5/1 = 1/x | cross multiply

1.5x = 1 so x =1/1.5 = .666666666666667 = 2/3. Each hen lays 2/3 egg per day.

6 hens lay 6*2/3 = 12/3 = 4 eggs per days.
That’s 7*4 = 28 eggs in 7 days.

So, in other words, 3 hens lay 3 eggs in 3 days, yes?

The link addresses the 28/42 dichotomy.
Starts center of page 267.
Apparently not a new problem, from the date of the work.

Because it’s the easiest shape to pass through a chicken’s butthole?

You have to break a few eggs to make a yolk, a *bad* as that. :)
