I have two Buff orpingtons. They are just a few days over 3 weeks. Same hatchery and born same day. One has red under her beak, and a larger comb (and is a bit heavier). Can you tell at this age?

This is the suspected rooster.
I am going to have 6 hens in a backyard coop. The coop will be inside an enclosed run that is 10'x12' for a total of 120 square feet enclosed, and it will be covered as well.
The coop itself will be 4x4 and 2.5-3' tall (it will slope from 3' to 2.5') so it will have 16 sq feet of floor space...
