They can either be wood or aluminum. I encourage you to use a wood one. If not, I will make fun of you like I do my good friend Bill Booker at LaSalle-Peru H.S. for using his aluminum one. If you choose the wood fungo, I would recommend taping the barrel.  If you hit a good number of fungoes, the tape will increase the durability of the bat. I took the tape off of one once. The barrell was like sawdust, but I re-taped it and it was ready to go.  One season, I figured it out, between the  high school, American Legion, an junior high seasons I had hit over 10,000 fungoes. Tape it up!
Fungo bats typically weigh between 17 to 22 ounces and may be as long as 37 inches, making them longer than most bats used for hitting. According to Pro Bats, a typical professional baseball player uses a bat that is about 34 inches long and weighs about 32 ounces, although there is considerable variation. Fungo bats not only are longer than regular bats, they also are skinnier. Like regular bats, fungo bats can be made of metal or wood.
Many players "bone" their bats, meaning that before games, they rub their bats repeatedly with a hard object, believing this closes the pores on the wood and hardens the bat. Animal bones are a popular boning material, but rolling pins, soda bottles and the edge of a porcelain sink have also been used. Pete Rose had his own way of hardening his bats: he soaked them in a tub of motor oil in his basement then hung them up to dry.[25]
Break your team up into 2 or 3 teams. If you do 2 teams you’ll need 8 or 9 on a team with a player for each defensive position. If you only have 8 on a team you can eliminate either the pitcher, catcher, or one outfielder based on what is a priority for your team that day.  If  you only have 12-15 players on your team break it up into 3 teams of 4-5. Then place two of the teams on defense and one team hitting fungoes. No matter what, have the teams and batting orders pre-made before practice. This will eliminate unnecessary downtime during practice.
Manufacturers position each bat's label over the mechanically weaker side of the wood.[9] To reduce chance of fracture,[9] and maybe deliver more energy to the ball,[10] a bat is intended to be held so the label faces sky or ground when it strikes the ball during a horizontal swing.[9] In this orientation, the bat is considered stiffer and less likely to break.[11]
Fungo bats are, simply put, a long, skinny, and lightweight baseball bat used for fielding practice. Typically, they are around 34 to 37 inches in length and between 17 and 24 ounces in weight, give or take a couple of ounces. They will also almost always feature a 2 1/4 inch barrel diameter to allow for more control during a swing. As you can tell, fungo bats are longer than a normal baseball bat and much more lightweight in comparison. Most fungo bats are going to be made up of ash wood while there are some maple and bamboo wood fungo bats, some composite wood fungo bats, and very few aluminum alloy fungo bats. Almost all of these designs will be under $100 with very few eclipsing that mark. 

To figure out who shoots first, players usually throw or roll a baseball to a certain object (usually at close range) and whoever is closest shoots first. The first person then gets to choose the first hole and tees off. To tee off (and for most shots) players hit the ball like they were playing baseball, but depending on the distance from the hole the player may choose to ‘putt’ the ball instead of hitting it. To putt the ball, the player places the ball on the cup (the end of the fungo bat), and can toss the ball from the cup in hopes of getting a more accurate shot.[1] In shooting or putting, the player must have one foot where the ball landed during the entire duration of their swing or putt, failure to keep the foot planted results in a loss of a stroke. Scorekeeping is identical to traditional golf; the player with the fewest strokes essentially wins the hole.[2] Players traditionally play nine or eighteen holes of fungo golf, and at the end the person with the fewest strokes in the set number of holes wins the game.[3]
