As there is 3 of them. Best thing you can do is lure them away from each other. Best bet is to make sure they split from the alpha. Kill the alpha unless you want it. Lure it into taming raft. 3 walls high. They will glitch through the walls so be careful. Then shoot. It took 60 or so arrows all headshots for a 50 one to go down. They are not easy to do solo. Have a rifle. I killed a 95 alpha with rifle.
