If you're worried about asking a duplicate question, you could search the site to see if it has been asked before. I've wanted to ask quite a few questions before but did not because I found that it was asked upon checking if the question has been asked or not. :P
TBH, most stuff like "Why isn't <x> evolving?" or "Why doesn't <y>'s eggs hatch <z>?" have probably already been asked, unless it is about a new generation that came out recently. :P
