asil/aseel vs viper...same thing?

So, where I work, I have many occasions to save chickens...mainly roos, but sometimes we get some girls in...especially after raids or around spring time.

One of my co workers rescued a group of game type hens, not knowing what type they were, she got online, and was told they are vipers...the birds she is discribing to me sound very much like an aseel/asil (how do you spell that?). So, my question is, are they the same bird?

oh yes, contrary to how the media paints us, we are a very forward thinking city. We have rescued many many games. In addition to the vipers, my co worker also has like 20 something game hens also from various raids.

Sadly, the roosters are not so lucky as the hens. It is against ordinance for any rooster to be in our city limits, but for the fighters, it is a liability unfortunately to send them anywhere  One guy actually came up and tried to steal someon else's roos right from our facility, and worse from others (Though I have personally sent many many non-raid roosters, many of them some variety of game or another to loving homes. Infact, there is a tail-less chap there right now (lost courtesy of yours truely...he had been running stray for months fending for himself, and I suprised him and caught him in the dark...kinda lost is tail feathers in the process). He is an old english of some sort I believe...he is going to a loving home tomorrow. He will be rooster to like 20 girls in another city).

The roosters are not the problem...its the humans.

SO, just from a picture you can tell what breeding line the particular bird belongs to?

That's what I kindof figured, but I figured it would be best to ask those that are in the know with these types of birds
