How Many Eggs Will Robins Lay?

The adult Robin is very, very easy to recognize because of that distinctive red breast. But juvenile Robin is actually very hard to identify. So it tends to be all brown, has quite yellowish streaks and spots. And the babies don't hatch out with a red breast, do they? That develops later as they mature. How many eggs will Robins generally lay? Oh, six to seven, generally. And will the male and female work together or will the male sort of play away? They saw something like that when they're bringing up the babies. The more vibrant the blue, the more time and effort and energy a male Robin will invest in providing for those eggs.
