yes you make some good points there, but have some flaws there too.
It is not always the fault of the buyer, Many new buyers do not know exactly what a 100% pure bird looks like, To be honest, it take a very well trained eye to distinguish certain species hens apart. That only comes with years of dedication to the species in question.
Other species can be crossed, and look right when you buy them, but 2 years down when they color up, you find out you have a cross.
Others yet, can be crossed and truly impure, but look correct. Red golds with amherts blood for example
These are all things a responsible breeder should keep track off and be able to give to the customer with 100% certainty.
Also as for the introduction of "new blood" as you called it, these dont work that way, once out crossed, they will never again be pure in the true sense of the word, they arent like chickens , where you can just get them close and call them good. They are either truly pure, or they are a hybrid, so fixing the blood that way is not the correct way.
The correct way with pheasant is to fine "new " blood from others pure stock, at this point in time, preferably imported stock, as most of the US lines are already watered down to the point of nearly loosing the species in it's true natural form all together.
Case again, the golden, aside from imported lines, most all now have some degree of amherst blood in them in their lineage somewhere. What does this do, well after decades of improper breeding, people tend to forget what a bird is supposed to look like in it's natural form, thus, the mules start becoming what people refer to as the true breed.
No you are right, we need to be grateful for everyone who is interested in "breeding" pheasants. And those with spare parts around always seem to cross breed, just to see what happens. I have no problem with it if this is where it ends. The problem arises, when a breeder starts to sell his stock of cross breeds to people because they think it looks cool, which yes, most do.
Now they breed these mutts, and give there buddy some, who doesnt have a clue what they are, again, just look cool.
Then they sell some or give them away etc etc etc.
The spread of crossed birds is where the problem comes from, not necessarily the creation of them, though without that, there would be no spread right.
Some are intentional, then again, like I said, some hens look very similar, so they can be accidental on new bies, parts, but again, a good breeder should have show and explained the difference to the new buyer so they would know better.
In the long run, most of these species of birds are endangered or at very least threatened in the wild. It is our responsibility as aviculturist to assure these captive birds stay as pure as humanly possible. In short, we all should be breeding with preservation of the species in mind, not a , well I bought it, no ones gonna tell me what I can or cant do with it attitude.
In those Case, people who intentionally want to have them just to "make" a new color or breed, no honestly we dont really need those keeping them, period.
If that's what you want your goals in pheasant keeping to be, then please, just dont get pheasants, go buy yourself a chicken or turkey and play God with them.
We've pretty much lost most all the truly pure muticus peafowl species here in the U.S already from the spaulding craze, there are a handful left, but not many, yet look how many are selling"java" on the internet, most dont even know what to really call them, that's what I was referring to with spreading down the line thing. They think they have pure javas, or any of the 3 species for that matter, but honestly, they have no clue what to look for to tell the difference, some call the emerald javas, LOL
Well, like you, I wasnt pointing fingers, just felt I put my counter point in there to maybe explain a little why true pheasant keepers get a little upset everyday when they get on-line and see stuff like this.
Again we should all be breeding with species conservation in mind with these, not a, lets see what happens when I do this.....
But if you do, and it's your call to do so, but please let the hybrids die with you, dont spread them and keep them away from breeding pures. Without some restraint, we are going to loose our captive populations, if isnt too late on some already
