Gundam:

Yellow hens and hens lay eggs faster, so you should look at them at most.

Because hens lay 1 egg every day, they are born with 10 eggs.

Because the yellow hen laid three eggs and rested for one day and laid five eggs after five days, the yellow hen laid 10 and 15 eggs.

A * * * laid 25 eggs. So two hens lay 25 eggs at most in 10 day.

Minimum:

White hens lay eggs the slowest, and hens lay eggs slower than yellow hens, so at least it depends on hens and white hens.

The hen 10 laid 10 eggs, and the white hen laid 1 0 eggs and rested for 3 days.

So eight days ago, I had a holiday for six days, and I laid two eggs, and two eggs were laid in the first eight days.

There are two days left 1 spawning, 1 rest, so there are two days left 1 spawning.

Together, it is 2+ 1=3 eggs.

So at least three eggs should be laid.
