Ive been playing with these blues for a couple of years now...feels like a whoooole lot longer, for some reason. Im on my second and third generation. In the first generation, I used several barred rocks, and in not paying attention, some of them had white legs instead of yellow, so I did end up with some white legs in my first generation. The roos I have used all have yellow legs. Seems the blue hens have very slatey legs, but the underneath of the feet will be yellow. The roos have much more yellow on their legs.
This is the blue roo I was using, at a young age:
And how he ended up grown up.
His legs got very slatey, tho they always had the yellow undertone and his bottoms of his feet were very yellow. He also got very mean, so he left.
The splash pullets had more yellow than the blues or blacks in their legs.
The blues and blacks have dark/slate legs, but the bottoms of their feet are yellow, for the most part. I did end up with some white feet bottoms, Im not using them for breeding.
With the first generation blue rocks that I hatched, I did get a lot of "cochin butts". They are not correct type as far as the breed standard goes, but Im still using them for breeding. My roosters have had good tails, and the barred rock girls that I used also imparted great tail carriage. So Im sure Ill eventually breed out the "cochin butt", but the color on some of those blues is so gorgeous, which is why Im continuing to use them in hopes I can keep the color and correct the tails.
A cochin-butted girl, probably a cross of the blue roo over one of the originals blue rock hens.
A better tailed girl, from the blue roo and a barred rock hen.
This is a black roo that Im using. Im not crazy about him, but he's the only black I have right now, so Im just using him to get some more black pullets.
One of my favorite black hens. I really love the blacks, but I dont have much to work with. I only have the one roo and 4 hens, and they dont like to lay much. I think Im going to try and produce a really good blue roo with my black hens and splash roo.
These birds are still a work in progress; Im also trying to get a little better size to them, since they are on the small side. So no, they arent perfect, but Im aware of the breed standard, and am trying to aim for that. I know theres not a lot of them around, so Im pretty much stuck with working with what I have.
