The problem being the way you worded it.Isn't it possible with Colosseum? It would not make sense that my Feraligatr is in my party because I don't remember ever getting an egg for it, or getting it off GT. In fact, the only egg I got was a Charmander egg.
The way your first post was written made it out that it was your Feraligator from Silver itself, not from Colosseum.
