Congrats on the chick!! I think you're right about it incubating before you got it--I guess in summer it stays warm enough that can happen. Anyway--the absolute best thing you can do right now is get your humidity way up in your incubator and sit tight. The more you mess with the little guy, the harder time he's going to have. He can live inside the shell like that for three or four days after pipping, so don't panic and rush him. He may easily take 36-48 hours from making the pip to hatching. As long as he is active and talking, he's probably fine. If you try to help him too soon he can bleed to death from rupturing veins in the membrane, or hatch with the yolk unabsorbed, which is highly dangerous.
So, sit tight and enjoy. It's hard to wait, but it will be sooooooo worth it!
