I see you at least acknowledge parthenogenesis as being a possibility in the turkey world. When you think about it, that idea is at least as absurd as a turkey x chicken hybrid, or a hybrid between turkeys and other species of birds. But parthenogenesis is a thing, however rare.I had read the second citation but did not see the first link because you cleverly added it your post after I had asked for sources.
The first article raises concerns about how true the results are and does bring up the concerns about parthenogenesis since any turkeys produced by parthenogenesis are male.
I am sure that you are going to continue to believe that there are successful turkey chicken hybrids. Personally, I have not seen any research that proves it can happen naturally. The fact that the turkey hybrid experiments were done a long time ago should tell you something but that isn't what you want to believe.
As far as wikipedia goes, it is a well known fact that there is a lot of false information posted on wikipedia.
Look. You said a turkey can't cross with another species, but you are wrong. Further stating that it "doesn't count" because it occurred in only one scientifically documented study, via artificial insemination, is moving the goal posts, so to speak. I can see why more scientists don't study this specific subject, because it is honestly a little bit irrelevant in the grand scheme of things.
I wasn't big on the Wikipedia citation either, hence my words "for whatever It's worth. Lol.
Here, check this out. I'll even quote the important part that pertains to our discussion, in case you don't want to read through it.

"Two adult hybrid birds available to us were male progeny of Belstville small white turkey hens artificially inseminated with semen from male chickens of the Dark Cornish breed. Morphological evidence of the hybrid status of the birds, already published in detail, includes the fact that their dark plumage resembles that of Dark Cornish chickens, whereas Beltsville small white turkeys are recessive white in color. Furthermore, the results of serological studies on their red cells are in accordance with their being interspecific hybrids."
These were not a product of parthenogenesis, they checked out via blood testing as being hybrids. Artificially inseminated or not, this did really happen.
I'm not saying, by a long shot, that there are turkey hybrids running around everywhere, but scientifically speaking, I absolutely cannot discredit such a hybrid as being possible.
