If they are from the white hen and the blue roo they could just be a lighter blue or lavender but I don't know how you can get a lavender (what colors I mean;) ) splash is a really pretty color in my mind:) ! Are the other cochin babies outside yet? I love the banty cochins, I am getting a birchen cochin bantam soon!
I have a splash pullet about 4-5 months and she's a real beauty! I have the bantys outside already, i thought that they didn't have enough nutrients when they were chicks because they stayed a real small size! Lol! Until I realized that they were bantys. They turned 2 months on the 15th. I didn't want them outside but they're in a secure coop. I have a blue cockerel that I think is a banty for sure he's much smaller than my black pullet. I'll take some pics later on(hopefully)
