Hi congrats on your first chick isn't it amazing!! Try not to panic about the pip in the wrong end make a note of time it pipped if you can. From pipping you should wait at least 12 hour before intervention. As you say it has an air hole. Please try and read assisted hatching post it's on the incubating and hatching page sorry but it won't let me add the link I am on iPad and it's not playing ball. Oh and breathe everything will be fine.

keep me posted will be on for next few hours and love the pic of your new chick. I think I might have to get my incubator out again it's making me broody.:cd
That's excellent news so pleased for you glad the wrong way one hatched ok and mushy one seem fine. Yes it does get rather noises and rough in the incubator!!!! Post some pics when they are done would love to see them.
