With my blue copper (BBS) line I started out with 3 splash coppers (Bev Davis supposedly) but their egg color wasn't great, one laid a 4 and the other 2 laid lighter than a 4. I bred them to Mud, my original line B (FRF) black copper cock bird and that is how Lucille, my best blue copper hen was produced. She is the only one I kept to breed from. Her eggs are a 4. I bred Lucille to Maximus (from my black copper line C) who was her half brother, they share the same sire but have different mothers. They are the parents of the cockerel I just posted a pic of, and the blue copper chicks I've produced this year. What I hope to achieve with this generation first and foremost is darker egg color because both Lucille and Maximus are half line B which is my darkest laying line. They are 1/2 siblings but share the same B line sire so I think that will reinforce darker egg color in this years chicks. I hope all that makes sense. I also managed to achieve nice lacing on most of my blue copper chicks so I am very happy with what I see so far.
