    I understand way too little about genetics, so I have wondered with colombian rocks, being as colombian is a dominant gene, could I breed a white rock hen to my colombian rock roo and get at least some colombian chicks? I believe that colombian is supposed to be over a silver instead if white gene, would I need the white rock to carry a silver gene? Often white covers many other color genes would these effect the cross?

    I have been wondering as I would like to improve my flock and have no source for more colombian rocks, and my flock throws a heavy percentage (around 80%) of roos

    What do you consider to be a pure columbian rock? What are you criteria? I know of I couple of lines that crossed columbian and white and got show marked columbian bantams. They did produce some other almost bichen colored ones as well.

    Quote:so are you taking about bantams or large fowl.
    http://www.circlepondfarm.com/sign pics 038.jpg - i would consder that a pure columbian rock. with very little black on any place on the bird. also white birds can have many genes hiding under the white.

    That is very close to my birds, except my birds have brighter yellow shanks. They are as close to pure as I have ever seen. I will try to find a pic. Either way, it is the only stock I can get, it is where I will start from.

    Oh and to answer the earlier question, they are large fowl

    Yes as far as I have seen there are very few colombian rocks in the US. I don't know of any others, but as far as I can tell these are the real thing. Either way they are a good starting point, but I only have my original 2 roos and 2 hens, and quite a few cockerels. I hatch alot of eggs, but seem to keep getting roos. If god forbid something happened to my hens I would be out of luck unless I could breed back to a white. I would also like to add some different blood into the line, and with only 2 related pair, there isn't much diversity. I figure since they are all plymouth rocks, the main difference is color. There has to be a way! I don't have a source for real Colombian rocks without going to canada, and for me at the moment that isn't an option

    I found some pics
