I was wondering if these genes can be triggered again, artificially or naturally

If you look at the bone structure of a bird, you will find that they have fingers. They obviously have tails (ever seen a peackock?), but their wings "hide" their "fingers," and they only have three of them. The other two were "lost" evolutionarily.

Of course they retain the genes, but they are just organs that have become less evident and used through evolution. Fingers and tailbones in birds are similar to human fingers and tailbones through common ancestry, but in short, they are vestigial organs. They are present, but provide no real use or benefit to the bird.

they already have tails... except that they are covered with feathers. fingers, on the other hands, must be vestigal organs to the bird.
