I have 4 black copper marans that are 7 weeks old tomorrow and I know one is a definite hen, and one is a roo, but not sure about the other two. Hoping they're both hens! Sorry the pics are so dark, they like to spend time in the shade a lot! Bird #1 This one is unknown to me! Thinking hen right now.. Also a little skiddish. Bird #2 This one is also unknown as well, sorry pic isn't great, he/she is a little skiddish, and is the smallest of all 4 of them. Looked exactly like my roo a couple weeks ago but my roo has gotten a lot bigger and this little guy is still.. Well.. Little lol I know this one's a hen. She loves to come and cuddle with me and is always right at my feet when I'm outside. Bird #4 this one is our roo. we'll be keeping him so his name is Zeppelin.
