Fun looking birds there, would love to see some more recent pics too!
For the poster who said that if the roo was the barred one all the chicks would be barred - not so! Guess it depends on how many genes etc but I have a blue barred cochin roo and I have two pullets from him over BO hens and they are both not barred! Both have lighter heads, the one is more gold with a dusky darker body and the other has a 'dark gold' head with what looks almost a dark brown colour body. No barring at all. I know that the Buff genes work really differently than a lot of the others and can throw in some unusual colours.... for what it is worth, I am by no means knowledgable ... just learning in little steps.
sorry duplicate post
The reason you got different colors is because BLUE barred birds are different than BLACK barred birds. Blue acts differently than black, because, when crossed with certain colors, can produce more variety in colors, such as khaki, fawn/dun, blue, black, platinum and splash. Blue, black and splash being the usual colors. Fawn, khaki, and platinum are too complicated for me to list off the bat. Those are the colors that most likely popped up with your girls. But because the rooster was BLUE barred, the color patterns were different.
