Hi. My son and I are new to raising chickens. We did a lot of research on breeds before starting our coop. We have three orpingtons, two silkies, and a SL Wyandotte. I'd love your thoughts on whether you think we have roos or pullets. I understand you won't be able to comment on the silkies. I will say the chocolate silkie and black orpington have faced off several times. And the same black orpington and white silkie appear to be an item. Black Orpington and wyandotte are 7 weeks. Other Orpingtons are 6 weeks. Thank you in advance to those who comment.
