When I got home from work my 2 sebright roosters were in the coop "making" nest in the bedding. Then they would "sit" in them like a chicken would to lay an egg.(I think we haven't had any eggs yet). The three girls were out free ranging by themselves. I've never seen this before the roosters are always so protective of them. They are all 18 weeks old now, and I know that its getting time to get rid of one of the roosters because they are beginning to fight.
