These chicks are just over six weeks old. I'm thinking out of the five left I have maybe two hens and three roos. I think they are roo's because they look to have large combs that are more red than the others they are also developing more. Also they are starting to challenge each other, not sure they would do that at this early age but what do you think? I might keep one Roo others will have to go.. the ones I hatched out this month are too early to tell. I hope I'm not surrounded by Roo's.. Blue Maran I think hen and roo?? Blk Maran roo?
