BCM or Blue Maran Rooster

[dhilling]

Hello,
I have 3 young roosters and 6 marans hens(Blk/BCM/Blue). of the 3 roosters I have a BCM and 2 blues. I don't believe the blues are copper because they have more of a white color neck. They just started being aggressive and I only want to keep 1. All nice looking birds. The one blue is huge compared to the other 2. born 1 month apart (I hatched them). anyway, of the 3 which one should I keep? the one smaller blue I'm sure he's gone, but the big blue and big copper are what I'm trying to decide. is there something I should look for? they all came from dark eggs, feathered feet. which is what I want to keep. I do have 1 wheaten Marans that lays a very dark egg. but I've been told not to cross her.

Start by removing the more aggressive ones to a different pen and see how the remaining one behaves without the others. Are they aggressive with you or the hens? I'm no marans expert but I would keep the one that acts the best towards you and the hens.

If breeding to standard is a factor, incorrect coloring would be an obvious cull.

If they have more of a white looking collar, they may be blue birchen marans, rather than blue copper. Here's a pic of some of my Blue Copper grow outs (with other birds

and an AC photo bomb). Sadly, the boys in this pic have too much leakage of the copper on their chests.
