The best way to domesticate this monster chicken, is:

--- You catch him in a trap made of stone pillars or even wood (two nrvas are enough) and some wooden ramps.

--- You can use (Tripwire Narcotic Trap To give it numbness faster) and some tranquilizer arrows or tranquilizer darts.

--- Having laid it to the ground, it is best domesticated with kibble or crops combined with sooting balm(if you use crops, because it will take many hours).

--- remember to have enough narcotics or biotoxin.

--- Sooting balm you can get from missions or by giving artifacts to the obelisk.
