The reason for the crossing is that a preservationist crossed their Iowa Blues in the not so distant past to increase vigor resulting in mossiness. This color leakage is not that easy to get out of a line. Since (as I understand it) this preservationist had the main lines and most everybody (I don't know if it is everybody or not so I am stating most) has Iowa Blues from this line. The Iowa Blue should have a nice crisp silver color penciling and for the cock bird, hackles and saddles. Most of what we see are brassy colors. Some are looking at crossing these birds with others that have the Silver gene (Silver Penciled Rocks, Silver Sussex, ...)to try and get the color and size back to what it should be. By careful culling, within 5-10 years of selective line breeding, one should be able to produce an Iowa Blue that is correct in color and size.
I got one pullet from a set of
ebay eggs that has nice silver coloring. She is about 16 weeks old as are two other pullets that I have but they have the mossiness.
So, Iowa Blue breeding stock that I have include:
1 Iowa Blue Cock
6 Iowa Blue Hens
3 14-16 week old Iowa Blue Pullets (1 of which is not related to my other Iowa Blue birds for at least 2 generations)
3 Iowa Blue chicks hatched 10/15/2011
More eggs in the incubator due to hatch anywhere from today through November 6, 2011. I have been swapping and selling my Iowa Blue eggs trying to increase interest in them and when I do not have orders, I set what I have left. I am hoping for at least one cockerel from these recent chicks that will be able to go in with his mother and aunts and I would like to put my cock bird in with my pullets. My hens and 2 of my pullets have a lot more mossiness than my cock bird. and the one pullet. I am planning to use an A-E pen type of line breeding on all of my birds. With my Iowa Blue I may alter this some as to work on the color. The chicks that hatched Oct 15 are the first Iowa Blue chicks that I know are pure from my flock. I may have some others, but they were running in my laying flock while I constructed their breeding pen and I hatched these eggs to try and build a larger laying clock as well as take the chance that I would get some pure Iowa Blues.
The following is a quote from Sandhill
The breed was in desperate need of new blood and I have been working for the past few years to introduce new blood. There is still a slight possibility of an off-type bird.
