Sidewing, Those new beautiful birds you just got, are they local? Or did you have to get them shipped in? The gentleman you noted as the seller is outside of my circle of knowledge, so I was wondering if he is a distant breeder or local. And then I am supposing that you are not so much into hatchery birds as a way to get proper type and conformation, coloring and such. This is what I have come to see… if one wants the real article, you have to pony up with the cash. I have also come to realize it is perhaps the less expensive route to pay up front. Off hand and or from new eyes, that might not make sense, but where you are dealing in years, to grow out and see what one has, and then change and try again, you can loose ten years in a hurry, and not make any progress.
I have to tip my hat to you for what you are doing. I openly applaud those whom endeavor to improve a breed or strain of bird(s). If the question is not to be answered here would you please pm me? I see on the KSL classified adds there is a flock of Icelandic birds for sale, if anyone has an interest in these. I thought that chickens were as common as well 'chickens,' but good quality birds are sort of hard to find, and when found they are of a price worthy of their quality. Some parts of the hobby are not for the faint of heart.
Has anyone fed C.O.B to their birds? I saw some the other day while I was in Cal Ranch and wondered how the birds might like it. C.O.B. is corn/oats/barley and I think it is for horses and perhaps sheep or goats. But a lot of different feeds can be feed off label to your birds. I try to use as many different grains in my scratch as I can. I feel that offering a wide variety of seeds/grain are good for the birds. Each type has 'something' in it that is a little different, even milo, which I do not like much.
Nice day for the time of year,
