...No scab writer was credited during JF you idiot. If they were credited afterwards, they'd be walking targets.
Where the heck did this "info" come from? It's embarrassingly retarded crap, and you're the fool for believing it.
The writer's strike meant WGA writers were not allowed to write for any productions. One of the main reasons why the strike affected television the way it did, was because the SAG then told and forced all its members to refuse working on non-WGA scripts.
This meant that even if a studio hired non-WGA writers, and got them to write scripts, none of the actors would work on them. Scrubs is a good example, where Bill Lawrence hired two scab writers, but none of the cast were prepared to work on their scripts, and so they binned them.
Power Rangers is a non-SAG series. This means the SAG rules didn't apply to PR, and so Disney and Bruce could easily enough hire a bunch of non-WGA writers without any union drama.
That's it. So if Judd Lynn wrote an episode of Jungle Fury, he would have been credited for it. There's not a single reason why he wouldn't have been, because he's not WGA, and therefore not a "walking target".
(Whichever moron originally used the term "scab writer" to describe PR's temporary writers was wrong. To be a "scab", you need to break union rules, and PR didn't.)
Also important to note, it was a "writer's strike" not a "producer's strike", so Bruce was still producing the series. Nobody came and replaced him as the showrunner.
EDIT: And before you start with the whole "how do you know this", I know because the Disney series I was working on was in exactly the same situation. It was a WGA-written, non-SAG series, and we had "scab" writers come in (all non-WGA) and they were all credited for their work.
