Hi Wayne. Welcome to the forum.
Rather than asking on a sticky, you will get more help if you post a new thead. Go to this page
and click on the "New Thread" button. It's blue, above the posts and below the ads on the left side.
Then give us some more details. Is this a new baby that has never eaten? Is this an older snake? Is this a frozen thawed or freshly killed mouse? All the information you can give will help get good answers.
