I've just discovered a crack in one of my ceiling joists. It starts from the bottom of the joist and extends half way towards the top. Since the crack is near the middle of the span I think I would better fix it before I install the drywall. Anyone knows how to fix or stabilize it? Thanks in advance.

You could sister a similarly sized piece of wood 10 feet long to it, using 16d nails or 3" wood screws with construction adhesive and a double row of nails or screws on 6" centers.

agree but ensure that the joist isnt saging by wedging a 2x4 or 2x6 between it and the floor to lift any sagging and making it level with the adjacent members. Then fasten 2x's on either side of the joist.
