I'd like to put a nice blue quad together. If I put some splash hens with a blue roo that would put out 50/50. Am I right? If thats the case I would have to say it is a b/s pen. I'm not sure but I thought at first I had a boy and a girl blacks but i'm thinking they may be 2 girls. The one I thought was a boy isn't showing any irridescent tail feathers like it loked like before it was beginning to show. I'll have to get some good pics of them both.
