Cool Cool Cool. The Jumbo Browns and the M Golds are what I have. But I am in the south and you are in the cold north. Interesting indeed that a poosible mutation could be happening in colder climate.
Somehow Julia and the other have made the M Gold Recessive or something, but it is bleeding out (the chamgaine coloring) I bet. Cool Cool Cool.
You need to get 3 males from her birds and have enough females for each from her birds. (Get other birds from other lines, later). One of each to experiment with. NO waite she gave you a M. Gold. You just need 1 male J Brown with recessive white and 1 male White with recessive M Gold. Better check past posts for building breeder cages.
I know M Gold is Dominant, but lets pretend it isn't for a few months. Lets pretend its Changing and Mutating or is changing is different instances (that we don't know yet) which makes it act like it is recessive.
The birds that have this coloring from her birds are they all female by chance? Are the M Gold that pop up from her stock all Males? Hummmmm.
We want to see pictures of the coloring of the M Gold too, though we might have to wait a few weeks for it to mature a bit. At least I do, I want to see it. Does it have the defined pattern of a Manchurian Gold or is the Manchurian Pattern washed out? You have seen her birds, do her Manchurians have defined patterns? Does her J Browns have the white/wheat color strips of color on their backs or are they Gold? You may have to visit her more often to see more of her babies. Oh, how many have been fed to the Raptors and they could poosibly carry a new Mutation or at the least a new color.
Are her A&M's mostly white or do they have a lot of blotches of color? I thought I saw A SPOT (not a blotch) of color on her back in the 3rd picture. How is her hatch rate? Does she seem to loose a lot of light colored babies prehatch, or just after hatch? (For instance the M Gold has a lethal part of it and a high hatch rate is not expected when breeding, MGxMG would loose approximately 25% of hatch). This information could help identify where the color is coming from. Brown or Gold.
I know everyone will think I have no idea what I am talking about, and that is very possible. But what if? What if the M. Gold is changing, mutating again? The Gold is a mutation after all. What is the difference between the first Fawn and Fawn 2 (yellows)? They are both Mutations. Could there be a Fawn 3 out there? Lets face it all the different colors are mutations or later dilutions of crosses of mutations. To me her birds look like diluted gold - maybe 4th generation or so. What if its the white that is bleeding into the Diluted Gold (chamgaine)? Then she should be able to get rid of the white by breeding back. Right? But she doesn't have enough birds to do that, yet.
Breeders, which one should she set with her girls first? Or should she set up 3 breeder pens one with each of her hens and then a control breeder pen. If she can breed more of this possible Mutation then eggs can get sold to other breeders. Who could also work on it. And that would be a way to prove it is a viable mutation or a viable new color.
mhwc56. Do you have an incubator? Doesn't matter, if you want more of these you HAVE to have one. Get a bunch of eggs from her and hatch them yourself, give her back what you don't want for breeding for her Raptor etc. Heck you two could start up a little business there, trading back and forth and selling the pretty ones or their eggs. At any rate, then you will have a nice selection to choose from for breeding. Even being selective in breeding a few birds you may not get what you want.
And another person is led onto the hatchaholic band wagon.
Sorry I went on and on but I do get excited sometimes, and I have waited and waited for new colors here in the states to mutate. Its not that I want to have them or breed them. But I find Mutations very interesting and look for Why there are Mutations happening. I truely hope it is a new color. Its interesting that different lighter colors are showing up now in the north and brighter colors and different varieties in the south.
I still think there are many varieties of white (I do not think that white is the dominant color in your bird, so I do not consider it an white) that need to be named IF they can be breed true. But They Have to Breed True to be Named. I agree with that. You have to be able to reproduce it again and again. Like the Jumbo Brown that then became the Texas A&M. That some are trying to bring back in their true size. Or the Manchurian Gold. 3 separate and distinct varieties that are not always what they were supposed to be. But they are named varieties because they can be reproduced if one knows what to do.
Ok, I'll get off the soap box now. Someone elses turn.
