Okay Missy, deep breaths girl, relax. Yes it is obvious that the flies are the result of the dead bird.
When the hubby gets home, have him get a bunch of paper towels and 2 plastic bags. Pick up the bird with the paper towels and place it in the plastic bags. Tie it up good and put it in a garbage can if you can or deposit it somewhere far from the house.
As for the flies, go to your nearest hardware store and get some fly strips to hang in your house or the biggest fly swatter you can find.
